Macro Definition Documentation

◆ TIB_BUILTIN_MSG_FMT_KEY_FIELDNAME

#define TIB_BUILTIN_MSG_FMT_KEY_FIELDNAME "_key"

Built-in field name of the key field in a keyed opaque message.

◆ TIB_BUILTIN_MSG_FMT_KEY_MAXLEN

#define TIB_BUILTIN_MSG_FMT_KEY_MAXLEN (255)

Maximum length (in bytes) of the key field of a keyed opaque message.

◆ TIB_BUILTIN_MSG_FMT_KEYED_OPAQUE

#define TIB_BUILTIN_MSG_FMT_KEYED_OPAQUE "_keyed_opaque"

Built-in format name for keyed opaque messages.

Keyed opaque messages contain only a character string and a byte-string. Content matchers can match against the key field (character string).

This format name is valid as an argument to tibMessage_Create.

◆ TIB_BUILTIN_MSG_FMT_OPAQUE

#define TIB_BUILTIN_MSG_FMT_OPAQUE "_default_opaque"

Built-in format name for opaque messages.

Opaque messages contain only a byte-string.

This format name is valid as an argument to tibMessage_Create.

◆ TIB_BUILTIN_MSG_FMT_OPAQUE_FIELDNAME

#define TIB_BUILTIN_MSG_FMT_OPAQUE_FIELDNAME "_data"

Built-in field name of the data field in an opaque message or a keyed opaque message.

◆ TIB_BUILTIN_MSG_FMT_OPAQUE_MAXSIZE

#define TIB_BUILTIN_MSG_FMT_OPAQUE_MAXSIZE (12000)

Maximum efficient length (in bytes) of a built-in opaque message.

Larger payloads are less efficient.

This threshold also applies to the total payload of a keyed opaque message (including the key string, its null terminator, and the opaque data).

◆ TIB_MSG_FIELDS_FINGERPRINT_SIZE

#define TIB_MSG_FIELDS_FINGERPRINT_SIZE 20

Size in bytes of a message field fingerprint.

See also: tibMessage_GetFieldsFingerprint

Typedef Documentation

◆ tibMessage

typedef struct __tibMessage* tibMessage

Message object type.

Message objects are not thread-safe. Programs must not access a message from several threads simultaneously.

◆ tibMessageIterator

typedef struct __tibMessageIterator* tibMessageIterator

Message iterator object type.

When you do not know the format of a message at the time you design a program, your program can use a message iterator to traverse the fields of a message. For example, you can use this technique to output the complete content of an erroneous or unexpected message to a log file. (However, when you do know the format of an inbound message, then you can code the program to get each field in the most efficient manner.)

A message iterator presents all the fields that are actually set in a message object. The message format determines the order in which an iterator presents the fields of a message.

Message iterator objects are not thread-safe. Programs must not access a message iterator from several threads simultaneously.

An iterator becomes invalid when its message becomes invalid.

Enumeration Type Documentation

◆ tibFieldType

enum tibFieldType

Datatypes of FTL message fields.

Enumerator
TIB_FIELD_TYPE_OPAQUE	Opaque byte-string.
TIB_FIELD_TYPE_LONG	Long integer.
TIB_FIELD_TYPE_LONG_ARRAY	Array of long integers.
TIB_FIELD_TYPE_DOUBLE	Double floating-point number.
TIB_FIELD_TYPE_DOUBLE_ARRAY	Array of double floating-point numbers.
TIB_FIELD_TYPE_STRING	Character string.
TIB_FIELD_TYPE_STRING_ARRAY	Array of character strings.
TIB_FIELD_TYPE_MESSAGE	Sub-message (that is, a nested message).
TIB_FIELD_TYPE_MESSAGE_ARRAY	Array of sub-messages.
TIB_FIELD_TYPE_INBOX	Inbox.
TIB_FIELD_TYPE_DATETIME	DateTime.
TIB_FIELD_TYPE_DATETIME_ARRAY	Array of DateTimes.
TIB_FIELD_TYPE_UNKNOWN	Unrecognized type. tibMessage_GetFieldType and tibMessage_GetFieldTypeByRef return `TIB_FIELD_TYPE_UNKNOWN` to indicate that the field's type is not defined. For example, getting the field type for a NULL message returns this value. It is not legal for programs to supply `TIB_FIELD_TYPE_UNKNOWN` to any API call except tibFieldType_GetAsString.

Function Documentation

◆ tibFieldType_GetAsString()

TIB_API const char* tibFieldType_GetAsString	(	tibEx	e,
		tibFieldType	fieldType
	)

Return a string that represents a field type.

Parameters

e	The exception object captures information about failures.
fieldType	The call converts this type to a string.

Returns: a string corresponding the fieldType argument

See also: tibFieldType

◆ tibMessage_Acknowledge()

TIB_API void tibMessage_Acknowledge	(	tibEx	e,
		tibMessage	message
	)

Explicitly acknowledge a message.

When a durable subscriber object specifies explicit acknowledgement, the application program must acknowledge each message to the durable by calling this method.

When a durable subscriber object does not specify explicit acknowledgement, the FTL library automatically acknowledges the message when the application callback method returns.

For any message that arrives through a non-durable subscriber, this call returns without error (and without action).

Parameters

e	The exception object captures information about failures.
message	The call acknowledges receiving this message.

Returns: void

See also: TIB_SUBSCRIBER_PROPERTY_BOOL_EXPLICIT_ACK

◆ tibMessage_ClearAllFields()

TIB_API void tibMessage_ClearAllFields	(	tibEx	e,
		tibMessage	message
	)

Clear all fields in a mutable message.

After clearing all fields, you can re-use the message. The message format does not change.

This call is more efficient than creating a new empty message of the same format.

Parameters

e	The exception object captures information about failures.
message	The call clears all fields in this message.

Returns: void

◆ tibMessage_ClearField()

TIB_API void tibMessage_ClearField	(	tibEx	e,
		tibMessage	message,
		const char *	name
	)

Clear a field in a mutable message.

Clearing a field clears the data from a field in the message object, and flags the field so a subsequent send call does not transmit it.

Parameters

e	The exception object captures information about failures.
message	The call clears the field in this message.
name	The call clears the field with this name.

Returns: void

See also: tibMessage_ClearFieldByRef

◆ tibMessage_ClearFieldByRef()

TIB_API void tibMessage_ClearFieldByRef	(	tibEx	e,
		tibMessage	message,
		tibFieldRef	fieldRef
	)

Clear a field in a mutable message.

Clearing a field clears the data from a field in the message object, and flags the field so a subsequent send call does not transmit it.

Parameters

e	The exception object captures information about failures.
message	The call clears the field in this message.
fieldRef	The call clears the value of this field.

Returns: void

See also: tibMessage_ClearField

◆ tibMessage_Create()

TIB_API tibMessage tibMessage_Create	(	tibEx	e,
		tibRealm	realm,
		const char *	formatName
	)

Create a mutable message object.

Programs can use this call to create messages for sending.

Message objects are not thread-safe. Programs must not access a message from several threads simultaneously.

Parameters

e	The exception object captures information about failures.
realm	The call searches this realm for the format definition.
formatName	The call creates a message with this format. `NULL` is a special value, indicating an unnamed dynamic format (for use only in one specific message).

Returns: a new message object

See also: TIB_BUILTIN_MSG_FMT_OPAQUE (as formatName argument)

◆ tibMessage_Destroy()

TIB_API void tibMessage_Destroy	(	tibEx	e,
		tibMessage	message
	)

Destroy a message object.

A program that creates a mutable message must explicitly destroy it to reclaim its resources. (However, it is often more efficient to reuse a mutable message. For further details, see the book TIBCO FTL Development.)

If a subscriber has set the release to callback property, then the program must explicitly destroy all messages it receives through dispatch from that subscriber. Otherwise, the program must not destroy messages received through dispatch.

Inbound messages (and sub-messages) in callbacks belong to the FTL library; programs must not destroy them.

Do not destroy a message if the program needs a reference into that message – for example, a string pointer (from tibMessage_GetString) or an opaque pointer (from tibMessage_GetOpaque).

Destroying a message frees all resources associated with it.

Parameters

e	The exception object captures information about failures.
message	The call destroys this message object.

Returns: void

◆ tibMessage_GetArray()

TIB_API void* tibMessage_GetArray	(	tibEx	e,
		tibMessage	message,
		tibFieldType	arrayType,
		const char *	name,
		tibint32_t *	arraySize
	)

Get the value of an array field from a message.

The program must cast the return value appropriately. The values array is valid only for the lifetime of the message. Programs must not modify or free the array.

This table lists the valid array types.

Array Type Constant	Values Array Pointer Type
TIB_FIELD_TYPE_LONG_ARRAY	tibint64_t*
TIB_FIELD_TYPE_DOUBLE_ARRAY	double*
TIB_FIELD_TYPE_STRING_ARRAY	char**
TIB_FIELD_TYPE_MESSAGE_ARRAY	tibMessage*
TIB_FIELD_TYPE_DATETIME_ARRAY	tibDateTime*

Parameters

e	The exception object captures information about failures.
message	The call gets the field from this message.
arrayType	The program supplies the array type of the field.
name	The call gets the value of the field with this name.
arraySize	The call stores the number of array elements in this location.

Returns: void* The program must cast this return value to the appropriate pointer type (see the table above).

See also: tibMessage_GetArrayByRef

◆ tibMessage_GetArrayByRef()

		tibFieldRef	fieldRef,
		tibint32_t *	arraySize
	)

Get the value of an array field from a message.

The program must cast the return value appropriately. The values array is valid only for the lifetime of the message. Programs must not modify or free the array.

Returns: tibDateTime

See also: tibMessage_GetDateTime

◆ tibMessage_GetDeliveryCount()

TIB_API tibint32_t tibMessage_GetDeliveryCount	(	tibEx	e,
		tibMessage	message
	)

Get the delivery count of a message.

This value represents the number of times that a persistence server has delivered the message from a shared durable to any subscriber. The value 1 indicates the application is the first to receive the message.

The special value -1 indicates that delivery count does not apply. For example, the message is not in a shared durable, or did not arrive from a persistence server that tracks delivery count.

Parameters

e	The exception object captures information about failures.
message	The call gets the delivery count for this message.

Returns: the delivery count

◆ tibMessage_GetDouble()

TIB_API tibdouble_t tibMessage_GetDouble	(	tibEx	e,

◆ tibMessage_GetLongByRef()

TIB_API tibint64_t tibMessage_GetLongByRef	(	tibEx	e,
		tibMessage	message,
		tibFieldRef	fieldRef
	)

Get the value of a long field from a message.

◆ tibMessage_GetMessage()

TIB_API tibMessage tibMessage_GetMessage	(	tibEx	e,
		tibMessage	message,
		const char *	name
	)

Get the value of a message field from a message.

This call deserializes the sub-message value, caches the result with the message object, and returns a pointer to that sub-message. The sub-message is valid only for the lifetime of the parent message.

The program must not modify nor destroy the sub-message. The FTL library destroys the sub-message when it destroys the parent message (usually when the callback returns).

Calling this method repeatedly returns the same cached sub-message; it does not repeat the deserialization.

Parameters

e	The exception object captures information about failures.
message	The call gets the field in this message.
name	The call gets the value of the field with this name.

Returns: tibMessage

	)

Set an opaque (byte-string) field in a mutable message.

For efficiency, programs can set an opaque field without the expense of copying the byte-string.

tibMessage_SetOpaque copies the opaque value from your buffer into the mutable message object. The program may then modify the buffer without affecting the message.

In contrast, tibMessage_SetOpaqueDirect stores only a pointer to the data in the message object. The send call serializes the opaque data. If you change the data in the buffer before the send call, you must call tibMessage_SetOpaqueDirect again to ensure correct serialization. You must not deallocate the buffer until after destroying the message (that is, until after tibMessage_Destroy returns).

Parameters

e	The exception object captures information about failures.
message	The call sets the field in this message.
name	The call sets the value of the field with this name.
value	The call sets the field value in the message to be a pointer to this byte-string.

Set an opaque (byte-string) field by reference in a mutable message.

For efficiency, programs can set an opaque field without the expense of copying the byte-string.

tibMessage_SetOpaque copies the opaque value from your buffer into the mutable message object. The program may then modify the buffer without affecting the message.

In contrast, tibMessage_SetOpaqueDirect stores only a pointer to the data in the message object. The send call serializes the opaque data. If you change the data in the buffer before the send call, you must call tibMessage_SetOpaqueDirect again to ensure correct serialization. You must not deallocate the buffer until after destroying the message (that is, until after tibMessage_Destroy returns).

Parameters

e	The exception object captures information about failures.
message	The call sets the field in this message.
fieldRef	The call sets the value of this field.
value	The call sets the field value in the message to be a pointer to this byte-string.

		tibMessage	message,
		char *	buffer,
		tibint32_t	size
	)

Get a printable string that describes the contents of a message.

Programmers estimate the required size of the string buffer. If the buffer is too small (or NULL), the call fails, but returns the actual required size. The program can use this information to supply a buffer of the required size in the second call.

Parameters

e	The exception object captures information about failures.
message	The call produces a string description of this message.
buffer	The call stores the description in this string buffer.
size	The program supplies the length of buffer (in bytes).

		tibMessage	message,
		tibuint8_t *	byteArray,
		tibint32_t	byteArraySize
	)

Write a serialized representation of a message to a byte-array.

Programmers estimate the required size of the byte-array buffer. If the buffer is too small, the call fails, but returns the actual required size. The program can use this information to supply a buffer of the required size in the second call.

Programming Strategy:

Create an array you think is big enough.
Call tibMessage_WriteToByteArray.
If the returned size is bigger than your array, then call tibMessage_WriteToByteArray again with a larger array (at least the returned size).

Parameters

e	The exception object captures information about failures.
message	The call serializes this message.
byteArray	The call writes the serialized representation into this byte-array buffer.
byteArraySize	The program supplies the size of the buffer (in bytes).

Returns: the actual size of the serialized representation (in bytes)

See also: tibMessage_WriteToPortableByteArray; tibMessage_ReadFromByteArray

◆ tibMessage_WriteToPortableByteArray()

TIB_API tibint32_t tibMessage_WriteToPortableByteArray	(	tibEx	e,
		tibMessage	message,
		tibuint8_t *	byteArray,
		tibint32_t	byteArraySize
	)

Write a self-describing serialized representation of a message to a byte-array.

This call writes a portable form of the message, which you can use outside the originating realm. The portable form is larger than optimized forms, because it includes all format metadata (as with a dynamic format).

Programmers estimate the required size of the byte-array buffer. If the buffer is too small, the call fails, but returns the actual required size. The program can use this information to supply a buffer of the required size in the second call.

Programming Strategy:

Create an array you think is big enough.
Call tibMessage_WriteToPortableByteArray.
If the returned size is bigger than your array, then call tibMessage_WriteToPortableByteArray again with a larger array (at least the returned size).

Parameters

e	The exception object captures information about failures.
message	The call serializes this message.
byteArray	The call writes the serialized representation into this byte-array buffer.
byteArraySize	The program supplies the size of the buffer (in bytes).

Returns: the actual size of the serialized representation (in bytes)

	)

Create a message iterator object.

Parameters

message	The call initializes an iterator for the fields of this message.

Returns: a new message iterator object

See also: tibMessageIterator

◆ tibMessageIterator_Destroy()

TIB_API void tibMessageIterator_Destroy	(	tibEx	e,
		tibMessageIterator	messageIterator
	)

Destroy a message iterator object.

Destroying a message iterator object frees all the resources associated with it, but does not affect the message object.

Parameters

e	The exception object captures information about failures.
messageIterator	The call destroys this message iterator object.

Returns: tibMessageIterator

◆ tibMessageIterator_GetNext()

TIB_API tibFieldRef tibMessageIterator_GetNext	(	tibEx	e,
		tibMessageIterator	messageIterator
	)

Get the next field of a message iterator object.

This call advances the iterator to the next field of its message, and returns a field reference object, which refers to that next field. Programs can use that field reference object to get the field's name, type and value.

Warning: For efficiency, an iterator object reuses a single field reference object. Iterator calls overwrite that field reference object. Programs can use the field reference object with correct results only until the next call that changes the state of the iterator. That is, when you get the next field, reset the iterator, or destroy the iterator, then the field reference object changes too (which also invalidates any field name string you might have previously extracted from the field reference). Although field reference objects are usually thread-safe, this one is not thread-safe. Your program must not destroy this field reference object.

If the iterator has already presented the last field of the message, then this call throws the exception TIB_NOT_FOUND.

Parameters

e	The exception object captures information about failures.
messageIterator	The call advances this iterator to the next field.

Returns: a field reference to the next field

◆ tibMessageIterator_HasNext()

TIB_API tibbool_t tibMessageIterator_HasNext	(	tibEx	e,
		tibMessageIterator	messageIterator
	)

Determine whether a message iterator object can present another field.

This call returns true if a message iterator is ready to present another field.
This call returns false if the iterator has presented the last field (and has not been reset).

Parameters

e	The exception object captures information about failures.
messageIterator	The call checks this iterator.

Returns: tibbool_t

◆ tibMessageIterator_Reset()

TIB_API void tibMessageIterator_Reset	(	tibEx	e,
		tibMessageIterator	messageIterator
	)

Reset a message iterator object.

This call resets a message iterator to the beginning of its message (that is, the first field of the message).

Parameters

e	The exception object captures information about failures.
messageIterator	The call resets this message iterator.

Returns: void
