package com.dmurph.mvc.model;
Keeps track of if a model is dirty through calling the methods setDirty(boolean) and firePropertyChange(java.lang.String,java.lang.Object,java.lang.Object).

public abstract class AbstractDirtyableModel extends AbstractModel implements IDirtyableICloneable {
	private boolean dirty = false;

If the model is "dirty", or changed since last save.

	public boolean isDirty(){
		return ;

	public boolean setDirty(boolean argDirty){
		boolean oldDirty = ;
		 = argDirty;
		return oldDirty;

	protected void firePropertyChange(String argPropertyNameObject argOldValueObject argNewValue) {
		if(argOldValue != null && !argOldValue.equals(argNewValue)){
			 = true;
		}else if(argNewValue == null && argNewValue != null){
			 = true;
	public abstract ICloneable clone();
