propertyIsCached
This flag is set when the callback Audiofilestream_propertylistenerproc is invoked in the case that the value of the property has been cached and can be obtained later.
Declaration
static var propertyIsCached: AudioFileStreamPropertyFlags { get }Discussion
If this flag is not set, get the value of the property from within this callback or set the cacheProperty flag to instruct the parser to begin caching the property data. Otherwise, the value will not be available after the callback returns.
