Implements AudioInfoSupport.

Reimplemented in AdapterPrintToAudioOutput, and AdapterAudioStreamToAudioOutput.

audioInfoOut()

virtual AudioInfo audioInfoOut ( )

inlinevirtualinherited

provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream

flush()

void flush ( )

inlineoverridevirtual

Reimplemented from AudioOutput.

isDeletable()

virtual bool isDeletable ( )

inlinevirtualinherited

If true we need to release the related memory in the destructor.

Reimplemented in AdapterPrintToAudioOutput, and AdapterAudioStreamToAudioOutput.

operator bool()

virtual operator bool ( )

inlinevirtualinherited

write()

virtual size_t write ( const uint8_t *  data, size_t  len  )

inlineoverridevirtual

Implements AudioOutput.

writeSilence()

virtual void writeSilence ( size_t  len )
