Detailed Description

Interface defintion for a Streaming Graph.

Definition at line 58 of file streaming_graph_intf.h.

Member Enumeration Documentation

◆ tStreamingState

enum tStreamingState : uint8_t

State Levels for the Streaming Graph as a Top-Level Graph.

Enumerator

State_Constructed

Constructed state.

The Streaming Graph is ready to add objects These objects will be constructed immediately while the IGraph::AddNamedGraphObject() call.

See also: section_streaming_graph_state, IGraph::AddNamedGraphObject()

State_Initialized

Initialized state Every data connection is established.

The sources and sinks are ready to stream.

See also: subsection_streaming_graph_init_method

State_Streaming

Streaming state Usually all source and sink streaming data.

See also: subsection_streaming_graph_start_streaming_method

Definition at line 67 of file streaming_graph_intf.h.

Member Function Documentation

◆ GetState()

virtual tStreamingState GetState ( )

pure virtual

Gets the state of the Streaming Graph.

See also: section_streaming_graph_state

Returns: The state currently valid.

Remarks: The current state will be returned with the right value only if a state change was successfully completed.

◆ SetState()

virtual tResult SetState ( tStreamingState eState )

pure virtual

Sets the state of the Streaming Graph.

See also: section_streaming_graph_state

Parameters

eState [in] The State to set.

Returns: Standard result code which depends also on errors occures within sink and source implementations.
