- (NSArray *) getMessageArrayField: (NSString *) name

Get the value of a message array field from a message.

Parameters

name	Get this field.

Returns: The value of the field, if the field is present and has type eFTLFieldTypeMessageArray; nil otherwise.

- (eFTLMessage *) getMessageField: (NSString *) name

Get the value of a sub-message field from a message.

Parameters

name	Get this field.

Returns: The value of the field, if the field is present and has type eFTLFieldTypeMessage; nil otherwise.

- (NSData *) getOpaqueField: (NSString *) name

Get the value of an opaque field from a message.

Parameters

name	Get this field.

Returns: The value of the field, if the field is present and has type eFTLFieldTypeOpaque; nil otherwise.

- (NSArray *) getStringArrayField: (NSString *) name

Get the value of a string array field from a message.

Parameters

name	Get this field.

Returns: The value of the field, if the field is present and has type eFTLFieldTypeStringArray; nil otherwise.

- (NSString *) getStringField: (NSString *) name

Get the value of a string field from a message.

Parameters

name	Get this field.

Returns: The value of the field, if the field is present and has type eFTLFieldTypeString; nil otherwise.

- (BOOL) isFieldSet: (NSString *) name

Determine whether a field is present in the message.

Parameters

name	The method checks for this field.

Returns: YES if the field is present; NO otherwise.

+ (eFTLMessage *) message

Create an eFTLMessage.

Returns: A new eFTLMessage.

- (void) setField:	(NSString *)	name
asDate:	(NSDate *)	date

Set a date field in a message.

Parameters

name	The call sets this field.
date	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asDateArray:	(NSArray *)	dateArray

Set a date array field in a message.

This method makes an independent copy of the array, and adds the copy to the message. After this method returns you can safely modify the original array.

Parameters

name	The call sets this field.
dateArray	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asDouble:	(NSNumber *)	number

Set a double field in a message.

Parameters

name	The call sets this field.
number	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asDoubleArray:	(NSArray *)	numberArray

Set a double array field in a message.

This method makes an independent copy of the array, and adds the copy to the message. After this method returns you can safely modify the original array.

Parameters

name	The call sets this field.
numberArray	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asLong:	(NSNumber *)	number

Set a long field in a message.

Parameters

name	The call sets this field.
number	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asLongArray:	(NSArray *)	numberArray

Set a long array field in a message.

This method makes an independent copy of the array, and adds the copy to the message. After this method returns you can safely modify the original array.

Parameters

name	The call sets this field.
numberArray	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asMessage:	(eFTLMessage *)	message

Set a sub-message field in a message.

This method makes an independent copy of the sub-message, and adds the copy to the message. After this method returns you can safely modify the original sub-message and its contents.

Parameters

name	The call sets this field.
message	The call sets this value. To remove the field, supply `nil`.

- (void) setField:	(NSString *)	name
asMessageArray:	(NSArray *)	messageArray

Set a message array field in a message.

This method makes an independent copy of the array and messages, and adds the copy to the message. After this method returns you can safely modify the original array and its contents.

Member Data Documentation

- (NSString* const) eFTLFieldNameDestination

Message field name identifying the destination on which messages are published.

To publish a message on a specific destination include this message field using setField:asString:.

To subscribe to messages published on a specific destination use a matcher that includes this message field name.
