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]pGraphObjectThe item to add.
[in]ui32OrderNumberThe initialize order number of the item.

INamedGraphObject
Returns
Standard Result Code
Return values
ERR_INVALID_ARGNo name set for graph object.
ERR_RESOURCE_IN_USEThere is already a graph object with the name.

Reimplemented in graph< INTERFACE >.

◆ RemoveNamedGraphObject() [1/2]

tResult RemoveNamedGraphObject ( const char *  strName)

Removes a named Object from the Filter Graph.

Parameters
[in]strNameName of the item to remove.
Returns
Standard Result Code
Return values
ERR_NOT_FOUNDNo item with the name strName exists

◆ RemoveNamedGraphObject() [2/2]

virtual tResult RemoveNamedGraphObject ( const ucom::ant::iobject_ptr< INamedGraphObject > &  pGraphObject)
virtual

Removes a Named Graph Object by instance.

This virtual function must be overwritten by any derived class.

Parameters
pGraphObjectthe Graph Object to remove
Returns
tResult
