Interface MetroEvent

All Superinterfaces:

MetroDumper, MetroEventDumper, MetroEventInFrames, MetroEventProcess

All Known Implementing Classes:

DefaultMetroEvent, DefaultMetroEventMidiEvent, MetroMessageEvent

public interface MetroEvent
extends MetroEventProcess, MetroEventInFrames, MetroEventDumper

This interface provides common methods for objects that represents every notes in a bar. Bars are usually generated by the tracks. This interface is strongly related to MetroTrack.progressCursor(int, List) method; refer the method for further information.

These methods are called as a callback of JACKAudio processing; these method should return as soon as possible. The heavy processing that blocks for longer time than the current setting of JACK's frame rate causes JACK to XRUN.
