gio.Seekable Stream seeking interface. gio.Seekable gobject.GInterface tell can_seek seek offset type0 cancellableNone can_truncate truncate offset cancellableNone +-- gobject.GInterface +-- gio.Seekable gio.Seekable is implemented by gio.FileOutputStream, gio.MemoryInputStream, gio.FileInputStream and gio.MemoryOutputStream. gio.Seekable is implemented by streams (implementations of gio.InputStream or gio.OutputStream) that support seeking. tell Returns : the offset from the beginning of the buffer Tells the current position within the stream. can_seek Returns : True if this gio.Seekable can be seeked with the seek() method, False if not. The can_seek() method checks if the seek() can be used on this gio.Seekable. seek offset type0 cancellableNone offset : the offset that is added to the position determined by the type parameter. type : 0=current position, 1=start of the file, 2=end of the file. cancellable : a gio.Cancellable or None. Returns : True on successful seek, False otherwise. Seeks in the stream by the given offset, modified by type. If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. can_truncate Returns : True if this gio.Seekable can be truncated with the truncate() method, False if not. The can_truncate() method checks if the truncate() can be used on this gio.Seekable. truncate offset cancellableNone offset : the offset at which the stream should be truncated cancellable : a gio.Cancellable or None. Returns : True if successful, False otherwise. Truncates a stream with a given offset. If cancellable is not None, then the operation can be cancelled by triggering the cancellable object from another thread. If an operation was partially finished when the operation was cancelled the partial result will be returned, without an error.
