Member Function Documentation

bool shaka::media::ThreadedIoFile::Close ( )

overridevirtual

Flush() and de-allocate resources associated with this file, and delete this File object. THIS IS THE ONE TRUE WAY TO DEALLOCATE THIS OBJECT.

Returns: true on success. For writable files, returning false MAY INDICATE DATA LOSS.

Implements shaka::media::File.

Definition at line 58 of file threaded_io_file.cc.

bool shaka::media::ThreadedIoFile::Flush ( )

overridevirtual

Flush the file so that recently written data will survive an application crash (but not necessarily an OS crash). For instance, in LocalFile the data is flushed into the OS but not necessarily to disk.
