begin()

virtual void begin ( )

pure virtual

Reset actual stream and move to root.

Implemented in AudioSourceCallback, AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, AudioSourceURL, AudioSourceVFS, and AudioSourceSDFAT.

index()

virtual int index ( )

inlinevirtual

Returns the actual index of the stream.

Reimplemented in AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, AudioSourceURL, AudioSourceVFS, and AudioSourceSDFAT.

isAutoNext()

virtual bool isAutoNext ( )

inlinevirtual

Returns default setting go to the next.

Reimplemented in AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, AudioSourceURL, AudioSourceVFS, AudioSourceSDFAT, and AudioSourceCallback.

nextStream()

virtual Stream * nextStream ( int  offset )

pure virtual

Returns next audio stream.

Implemented in AudioSourceCallback, AudioSourceURL, AudioSourceSDFAT, AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, and AudioSourceVFS.

previousStream()

virtual Stream * previousStream ( int  offset )

inlinevirtual

Returns previous audio stream.

Reimplemented in AudioSourceURL.

selectStream() [1/2]

virtual Stream * selectStream ( const char *  path )

pure virtual

Returns audio stream by path.

Implemented in AudioSourceCallback, AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, AudioSourceURL, AudioSourceVFS, and AudioSourceSDFAT.

selectStream() [2/2]

virtual Stream * selectStream ( int  index )

inlinevirtual

Returns audio stream at the indicated index (the index is zero based, so the first value is 0!)

Reimplemented in AudioSourceURL, AudioSourceCallback, AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, AudioSourceVFS, and AudioSourceSDFAT.

setTimeout()

virtual void setTimeout ( int  millisec )

inlinevirtual

Sets the timeout of Stream in milliseconds.

Reimplemented in AudioSourceURL, and AudioSourceSDFAT.

setTimeoutAutoNext()

virtual void setTimeoutAutoNext ( int  millisec )

inlinevirtual

Sets the timeout which is triggering to move to the next stream. - the default value is 500 ms

toStr()

virtual const char * toStr ( )

inlinevirtual

provides the actual file name or url

Reimplemented in AudioSourceIdxSDFAT, AudioSourceIdxSDMMC, AudioSourceLittleFS, AudioSourceSD, AudioSourceSDFAT, AudioSourceSDMMC, AudioSourceSPIFFS, AudioSourceSTD, AudioSourceURL, AudioSourceVFS, and AudioSourceSDFAT.
