|  | REAL | aVolume,
|  | REAL | aPanning,
|  | UINT16 | aPriority
| ) | `[protected]`

| Initialization method. This should be called by all extending classes in their creation method.

XFCIMPORT INT XFcAudioStream::initialize | ( | FLOAT32 | aSamplingRate,
|  | UINT32 | aFlags,
|  | REAL | aVolume,
|  | REAL | aPanning,
|  | UINT16 | aPriority
| ) | `[protected]`

| Initialization method. This should be called by all extending classes in their creation method.

virtual XFCIMPORT void XFcAudioStream::pause | ( |  | ) | `[virtual]`

| Called when a pause() call is made to XFcAudio with this producer (callback).

virtual XFCIMPORT void XFcAudioStream::play | ( |  | ) | `[virtual]`

| Called when a play() call is made to XFcAudio with this producer (callback).

virtual XFCIMPORT void XFcAudioStream::resume | ( |  | ) | `[virtual]`
