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. | |
| virtual | 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) | |
