Member Function Documentation

bool shaka::media::LocalFile::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 30 of file local_file.cc.

bool shaka::media::LocalFile::Delete ( const char * file_name )

static

Delete a local file.

Parameters

file_name is the path of the file to be deleted.

Returns: true if successful, or false otherwise.

Definition at line 104 of file local_file.cc.

bool shaka::media::LocalFile::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.
