Return whether or not seeking is allowed in this input stream.
The defaut implementation returns FALSE, disabling seeking. Override the function to allow seeking of input streams.
Reimplemented from om::sound::base::MIDIInputStream.
Return whether or not this stream's current position can be moved by the specified time offset.
The defaut implementation returns FALSE, disabling seeking. Override the function to allow seeking of input streams.
Reimplemented from om::sound::base::MIDIInputStream.
Move the current position in the stream by the specified signed time offset in seconds.
This method attempts to seek the position in the stream by the specified time in seconds. The method returns the signed amount that the position in the stream was changed by. Thus, if seeking is not allowed, 0 is returned. Otherwise, the stream should seek as far as possible in the specified direction and return the actual change in position.
The defaut implementation returns 0, disabling seeking. Override the function to allow seeking of input streams.

Return the number of seconds remaining in the MIDI input stream.
The value returned must only be a lower bound on the total time left in the stream. events in the stream. This behavior is allowed in order to support never-ending streams which might not have a defined endpoint.
Implements om::sound::base::MIDIInputStream.

Return the current position of the stream in seconds relative to the start of the stream.
The returned value indicates the time offset of the current read position within the MIDI stream. For unbounded streams, this indicates the number of samples that have been read by the stream since it was opened.
Implements om::sound::base::MIDIInputStream.

Read MIDI events into the buffer for the next time interval of the specified length.
This method attempts to read events for the specified time interval from the stream into the buffer and then returns the total number of events that were successfully read. The stream's current position is incremented by the return value.
The timestamps of the returned MIDI events are specified relative to the start of the time interval.
Implements om::sound::base::MIDIInputStream.
