class Sound
Defined at line 18 of file ../../src/media/sounds/soundplayer/sound.h
Base class for |UndiscardableSound| and |DiscardableSound|, both containers for sound that
wrap a VMO containing raw LPCM audio content.
Public Methods
void ~Sound ()Defined at line 20 of file ../../src/media/sounds/soundplayer/sound.h
const zx::vmo & LockForRead ()Locks the sound VMO for reading, restoring its contents if it has been discarded. Locks may
be nested arbitrarily (with a mix of |LockForRead| and |LockForWrite|). Only the outermost
lock call has any effect aside from changing the nesting counter. There are no unexpected
side effects, but, of course, if the intent is to read valid data from the VMO, the VMO
should contain valid data.

const zx::vmo & LockForWrite ()Locks the sound VMO writing. If the VMO has been discarded, it is not restored. See the
comment for |LockForRead| above.

Protected Methods
void Sound (zx::vmo vmo, uint64_t size, fuchsia::media::AudioStreamType stream_type)Constructs a |Sound| from a non-discardable VMO.

void ApplyLockForRead ()Applies a lock for reading on behalf of |LockForRead|, which handles the nesting counter.
void ApplyLockForWrite ()Applies a lock for reading on behalf of |LockForWrite|, which handles the nesting counter.
void Removelock ()Removes a lock on behalf of |Unlock|, which handles the nesting counter.
