Member Function Documentation

AddNamedGraphObject()

virtual tResult AddNamedGraphObject ( const ucom::ant::iobject_ptr< INamedGraphObject > &  pGraphObject, int32_t  ui32OrderNumber  )

virtual

This is to intialize and build an FilterGraph.

See the INamedGraphObject and all derived default implementations within the SDK.

Items with the same ui32OrderNumber will initialized in order of AddNamedGraphObject call.

Parameters

[in]	pGraphObject	The item to add.
[in]	ui32OrderNumber	The initialize order number of the item.

Returns

Standard Result Code

Return values

ERR_INVALID_ARG	No name set for graph object.
ERR_RESOURCE_IN_USE	There is already a graph object with the name.

Reimplemented in graph< INTERFACE >.
