Reset actual stream and move to root.

Implements AudioSource.

end()

virtual void end ( )

inlinevirtual

get()

const char * get ( int  idx )

inlineprotected

index()

int index ( )

inlinevirtual

Provides the current index position.

Reimplemented from AudioSource.

isAutoNext()

Reimplemented from AudioSource.

isValidAudioFile()

bool isValidAudioFile ( fs::directory_entry  file )

inlineprotected

checks if the file is a valid audio file

nextStream()

virtual Stream * nextStream ( int  offset = 1 )

inlineoverridevirtual

Returns next audio stream.

Implements AudioSource.

operator[]()

Stream * operator[] ( int  idx )

inlineinherited

access with array syntax

previousStream()

virtual Stream * previousStream ( int  offset )

inlinevirtualinherited

Returns previous audio stream.

Reimplemented in AudioSourceFTP< ClientType >, and AudioSourceURL.

selectStream() [1/2]

virtual Stream * selectStream ( const char *  path )

inlineoverridevirtual

Returns audio stream by path: The index is not changed!

Implements AudioSource.

selectStream() [2/2]

virtual Stream * selectStream ( int  index )

inlineoverridevirtual

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

Reimplemented from AudioSource.

setAutoNext()

virtual void setAutoNext ( bool  flag )

inlinevirtualinherited

Reimplemented in AudioSourceCallback.

setFileFilter()

void setFileFilter ( const char *  filter )

inline

Defines the regex filter criteria for selecting files. E.g. ".*Bob Dylan.*"

setIndex()

virtual Stream * setIndex ( int  index )

inlinevirtualinherited

inlinevirtualinherited

Reimplemented in AudioSourceURL.

setPath()

virtual void setPath ( const char *  p )

inlinevirtual

Allows to "correct" the start path if not defined in the constructor.

virtual void setTimeout ( int  millisec )

inlinevirtualinherited

Sets the timeout of Stream in milliseconds.

Reimplemented in AudioSourceURL.

setTimeoutAutoNext()

virtual void setTimeoutAutoNext ( int  millisec )

inlinevirtualinherited

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

size()
