Detailed Description

This base implementation of a sample writer is able to write to one Sample Stream which is connected to ONE cOutPin.

The cOutPin it is registered to will call ISampleWriter::BeginStreaming while connecting.

Definition at line 34 of file samplewriter.h.

Constructor & Destructor Documentation

◆ cSampleWriter()

cSampleWriter	(	const char *	strName,
		const ucom::ant::iobject_ptr< const IStreamType > &	pStreamType
	)

inline

CTOR with name and type.

Parameters

[in]	strName	Name to set
[in]	pStreamType	Stream to set on the writer (deep copy is created)

Definition at line 58 of file samplewriter.h.

Member Function Documentation

◆ BeginStreaming()

tResult BeginStreaming ( ISampleStream & pStream )

inlineoverridevirtual

BeginStreaming will open the given Sample Stream for Writing while a connection is establishing.

Parameters

pStream [in] Sample Stream to open

Returns: Result Code depends on the implementation

Implements ISampleWriter.

Definition at line 63 of file samplewriter.h.

◆ ChangeType()

virtual tResult ChangeType ( const ucom::ant::iobject_ptr< const IStreamType > & pType )

inlinevirtual

Changes and writes a stream type reference to the opened ISampleOutStream.

Parameters

[in] pType stream type reference to change and write

Returns: Standard Result Code

Definition at line 112 of file samplewriter.h.

References cSampleWriter::m_pOutStream, and sample_streamer< ISampleWriter, cOutPin >::SetType().

◆ EndStreaming()

tResult EndStreaming ( )

inlineoverridevirtual

Sample Stream disconnected.

Streaming ends.

Returns: Standard Result Code. Depends on implmentation.

Implements ISampleStreamer.

Definition at line 82 of file samplewriter.h.

References cSampleWriter::m_pOutStream, object_ptr< T >::Reset(), and RETURN_NOERROR.

◆ Flush()

virtual tResult Flush ( )

inlinevirtual

Flushes a the opened ISampleOutStream.

Returns: Standard Result Code

Definition at line 128 of file samplewriter.h.

References cSampleWriter::m_pOutStream, and RETURN_ERROR.

◆ ManualTrigger()

tResult ManualTrigger ( )

inline

This is to Run a trigger call manually.

A Trigger to the Trigger Pipe on the Pin will be forwarded.

Warning: do not call this within a filter! You will destroy the runtimebehaviour provided by a the Trigger Pipe.

Returns: Standard Result of the adtf::base::IRunnable::Run

Return values

ERR_NOT_INITIALIZED The Pin is not set. use create_pin to make sure the pin is set

◆ SetStreamError()

virtual tResult SetStreamError ( tResult oErr )

inlinevirtual

Writes an error to the opened ISampleOutStream.

Parameters

[in] oErr errror to write to the stream

Returns: Standard Result Code

Definition at line 145 of file samplewriter.h.

References cSampleWriter::m_pOutStream, and RETURN_ERROR.

◆ Transmit()

virtual tResult Transmit ( const ucom::ant::iobject_ptr< const ISample > & pSample )

inlinevirtual

Transmits and writes a sample reference to the opened ISampleOutStream.

Parameters

[in] pSample sample reference to transmit

Returns: Standard Result Code

Reimplemented in cLegacyOutputPin.
