Public Member Functions

 ModifyingStreamAdapter (ModifyingOutput &out)
 
void addNotifyAudioChange (AudioInfoSupport &bi) override
 Adds target to be notified about audio changes.
 
virtual AudioInfo audioInfo () override
 provides the actual input AudioInfo
 
virtual AudioInfo audioInfoOut ()
 provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream
 
int available () override
 Read not supported.
 
virtual int availableForWrite () override
 
bool begin () override
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
void end () override
 
virtual void flush () override
 
bool isNotifyActive ()
 Checks if the automatic AudioInfo update is active.
 
virtual operator bool ()
 
virtual size_t readBytes (uint8_t *data, size_t len) override
 
virtual size_t readSilence (uint8_t *buffer, size_t length)
 Source to generate silence: just sets the buffer to 0.
 
virtual bool removeNotifyAudioChange (AudioInfoSupport &bi)
 Removes a target in order not to be notified about audio changes.
 
void setAudioInfo (AudioInfo info) override
 Defines the input AudioInfo.
 
void setNotifyActive (bool flag)
 Deactivate/Reactivate automatic AudioInfo updates: (default is active)
 
void setOutput (Print &out) override
 Defines/Changes the output target.
 
void setStream (Stream &in) override
 Defines/Changes the input & output.
 
size_t write (const uint8_t *data, size_t len) override
 
virtual size_t write (uint8_t ch) override
 
virtual void writeSilence (size_t len)
 Writes len bytes of silence (=0).
