Class DummyNoteEventParser

java.lang.Object

metdetection.parsing.DummyNoteEventParser

All Implemented Interfaces:

NoteEventParser

public class DummyNoteEventParser
extends java.lang.Object
implements NoteEventParser

A DummyNoteEventParser is used to save memory when we don't really care about the actual notes being parsed. Since an EventParser needs some NoteEventParser, we give it this one, which does nothing.
