Member Function Documentation

◆ addNotifyAudioChange()

virtual void addNotifyAudioChange ( AudioInfoSupport bi)
inlinevirtualinherited

◆ audioInfo()

AudioInfo audioInfo ( )
inlineoverridevirtual

Provides the last available MP3FrameInfo.

Implements StreamingDecoder.

◆ begin()

bool begin ( )
inlineoverridevirtual

Starts the processing.

Implements StreamingDecoder.

◆ copy()

virtual bool copy ( )
inlineoverridevirtual

Process a single read operation - to be called in the loop.

Implements StreamingDecoder.

◆ end()

void end ( )
inlineoverridevirtual

Releases the reserved memory.

Implements StreamingDecoder.

◆ operator bool()

virtual operator bool ( )
inlineoverridevirtual

checks if the class is active

Implements StreamingDecoder.

◆ readBytes()

virtual size_t readBytes ( uint8_t data,
size_t  len 
)
inlineoverrideprotectedvirtual

Implements StreamingDecoder.

◆ setInput()

void setInput ( Stream inStream)
inlineinherited

Stream Interface: Decode directly by taking data from the stream. This is more efficient then feeding the decoder with write: just call copy() in the loop

◆ setOutput()

virtual void setOutput ( Print out_stream)
inlinevirtualinherited

Defines the output Stream.

Reimplemented in StreamingDecoderAdapter.
