Detailed Description

A data grid metadata object contains metadata information about the data grid and the tables in the data grid.

A program that creates a data grid metadata object must explicitly call tibdgGridMetadata_Destroy to reclaim its resources.

Function Documentation

tibdgGridMetadata_Destroy()

TIBDG_API void tibdgGridMetadata_Destroy	(	tibEx	e,
		tibdgGridMetadata	gridMetadata
	)

Destroy a data grid metadata object.

Release all resources associated with this data grid metadata object.

Note that destroying a data grid metadata object invalidates all objects accessed from it. Do not rely on information retrieved from the data grid metadata object after it is destroyed. Such information must instead be copied before destroying the metadata object.

Parameters

e	The exception object captures information about failures.
gridMetadata	The data grid metadata object to be destroyed.

Returns

void

tibdgGridMetadata_GetGridName()

TIBDG_API const char* tibdgGridMetadata_GetGridName	(	tibEx	e,
		tibdgGridMetadata	gridMetadata
	)

Get the name of the data grid.

This will be the product version associated with the proxy that returned the data grid metadata.

Note that the string provided by this API will be destroyed when the data grid metadata object is destroyed.

Parameters

e	The exception object captures information about failures.
gridMetadata	The grid metadata object from which to get the data grid name.

Returns

On success, this call returns a data grid name string.
On failure, this call returns NULL.

tibdgGridMetadata_GetTableMetadata()

TIBDG_API tibdgTableMetadata tibdgGridMetadata_GetTableMetadata	(	tibEx	e,
		tibdgGridMetadata	gridMetadata,
		const char *	tableName
	)

Get the table metadata object by its table name.

Note that the table metadata object provided by this API will be destroyed when the data grid metadata object is destroyed.

Parameters

e	The exception object captures information about failures.
gridMetadata	The grid metadata object from which to get the table metadata object.
tableName	The name of the table to get the metadata.

Returns

On success, this call returns a table metadata object.
On failure, this call returns NULL.

tibdgGridMetadata_GetTableMetadataArray()

TIBDG_API tibdgTableMetadata* tibdgGridMetadata_GetTableMetadataArray	(	tibEx	e,
		tibdgGridMetadata	gridMetadata,
		tibint32_t *	arraySize
	)

Get all table metadata objects in the grid metadata.

Note that the array of table metadata objects provided by this API will be destroyed when the grid metadata object is destroyed.

Parameters

e	The exception object captures information about failures.
gridMetadata	The grid metadata object from which to get the table metadata objects.
arraySize	The call returns the length of the array (output).

Returns

On success, this call returns an arra of table metadata objects.
On failure, this call returns NULL.

tibdgGridMetadata_GetTableNames()

TIBDG_API const char** tibdgGridMetadata_GetTableNames	(	tibEx	e,
		tibdgGridMetadata	gridMetadata,
		tibint32_t *	arraySize
	)

Get the names of the tables in the data grid.

Note that the array of strings provided by this API will be destroyed when the data grid metadata object is destroyed.

Parameters

e	The exception object captures information about failures.
gridMetadata	The data grid metadata object from which to get the table names.
arraySize	The call returns the length of the array (output).

Returns

On success, this call returns an array of table name strings.
On failure, this call returns NULL.

tibdgGridMetadata_GetVersion()

TIBDG_API const char* tibdgGridMetadata_GetVersion	(	tibEx	e,
		tibdgGridMetadata	gridMetadata
	)

Get the data grid's product version string.

This will be the product version associated with the proxy that returned the data grid metadata.

Note that the string provided by this API will be destroyed when the data grid metadata object is destroyed.

Parameters

e	The exception object captures information about failures.
gridMetadata	The grid metadata object from which to get the version.

Returns

On success, this call returns the version string.
On failure, this call returns NULL.
