 public class MVCHashMap<K, V> extends HashMap<K, V> implements ICloneableIDirtyable{
 	private static final long serialVersionUID = 3144943839261154818L;
 	
 	private boolean dirty = false;

 
 	public void clear() {
 		 = true;
 		super.clear();
 	}

 
 	public V put(K key, V value) {
 		 = true;
 		return super.put(keyvalue);
 	}

 
 	public V remove(Object key) {
 		 = true;
 		return super.remove(key);
 	}

Does a shallow copy unless the values are com.dmurph.mvc.ICloneable.

 
 	@SuppressWarnings("unchecked")
 	public void cloneFrom(ICloneable argOther) {
 		HashMap<K, V> map = (HashMap<K, V>) argOther;
 		clear();
 		for(K key : map.keySet()){
 			V value = map.get(key);
 			if(value instanceof ICloneable){
 				put(key, (V) ((ICloneablevalue).clone());
 			}else{
 				put(keyvalue);
 			}
 		}
 	}

does a shallow copy unless the values are com.dmurph.mvc.ICloneable.

 
 	public ICloneable clone(){
 		MVCHashMap<K, V> map = new MVCHashMap<K, V>();
 		map.cloneFrom(this);
 		return map;
 	}

Just sets dirty to false, doesn't revert changes

	public boolean revert() {
		boolean oldDirty = ;
		 = false;
		return oldDirty;
	}

	public boolean isDirty() {
		return ;
	}

Just sets the dirty variable

	public boolean setDirtyboolean argDirty) {
		boolean oldDirty = ;
		 = argDirty;
		return oldDirty;
	}
