Public Member Functions

 MemoryOutput (uint8_t *start, int len)
 
virtual void addNotifyAudioChange (AudioInfoSupport &bi)
 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 availableForWrite () override
 
bool begin ()
 
virtual bool begin (AudioInfo info)
 
virtual void clearNotifyAudioChange ()
 Deletes all change notify subscriptions.
 
virtual void end ()
 
virtual void flush ()
 
virtual bool isDeletable ()
 If true we need to release the related memory in the destructor.
 
bool isNotifyActive ()
 Checks if the automatic AudioInfo update is active.
 
 operator bool ()
 
virtual bool removeNotifyAudioChange (AudioInfoSupport &bi)
 Removes a target in order not to be notified about audio changes.
 
virtual void setAudioInfo (AudioInfo newInfo) override
 Defines the input AudioInfo.
 
void setNotifyActive (bool flag)
 Deactivate/Reactivate automatic AudioInfo updates: (default is active)
