  Type Name Description
Public function Virtual void This can be used to increase the memory count for external features.
Protected function Virtual void This can be used to increment reference counted handles to audio chunks.
Public function Virtual FString Generate a memory report as a formatted string for this streaming manager.
Public function Virtual Const FAudioChunkHandle

GetLoadedChunk ( const FSoundWaveProxyPtr& SoundWave,
uint32 ChunkIndex,
bool bBlockForLoad,
bool bForImmediatePlayback
)

 Gets a pointer to a chunk of audio data
Public function Virtual void This can be used to decrease the memory count for external features.
Protected function Virtual void This can be used to decrement reference counted handles to audio chunks.
Public function Virtual int32

RenderStatAudioStreaming ( UWorld* World,
FViewport* Viewport,
FCanvas* Canvas,
int32 X,
int32 Y,
const FVector* ViewLocation,
const FRotator* ViewRotation
)

 Used for rendering debug info:
Public function Virtual bool

RequestChunk ( const FSoundWaveProxyPtr& SoundWave,
uint32 ChunkIndex,
TFunction< void(EAudioChunkLoadResult)> OnLoadCompleted,
ENamedThreads::Type ThreadToCallOnLoadCompletedOn,
bool bForImmediatePlayback
)

 Manually prepare a chunk to start playing back.
Public function Virtual void

SetProfilingMode ( bool bEnabled
)

 Whether to toggle a performance intensive profiling mode the streaming manager.
Public function Virtual uint64

TrimMemory ( uint64 NumBytesToFree
)

 This will start evicting elements from the cache until either hit our target of bytes or run out of chunks we can free.
