Example 1

	// copy the entity state into the state array and return true if the state has changed
	ClassMetadata metadata = sf.getClassMetadata( entity.getClass() );
	Object[] newState = metadata.getPropertyValues( entity );
	int size = newState.length;
	boolean isDirty = false;
	for ( int index = 0; index < size; index++ ) {
		if ( ( state[index] == LazyPropertyInitializer.UNFETCHED_PROPERTY &&
				newState[index] != LazyPropertyInitializer.UNFETCHED_PROPERTY ) ||
				( state[index] != newState[index] && !types[index].isEqual( state[index], newState[index] ) ) ) {
			isDirty = true;
			state[index] = newState[index];
		}

 * @param entity an actual entity object, not a proxy!
 */

	// todo : this call will not work for anything other than pojos!
	ClassMetadata cm = factory.getClassMetadata( entity.getClass() );

	if ( cm==null ) return entity.getClass().getName();

	Map result = new HashMap();

	if ( cm.hasIdentifierProperty() ) {
		result.put(
			cm.getIdentifierPropertyName(),
			cm.getIdentifierType().toLoggableString( cm.getIdentifier( entity, entityMode ), factory )
		);
	}

	Type[] types = cm.getPropertyTypes();
	String[] names = cm.getPropertyNames();
	Object[] values = cm.getPropertyValues( entity, entityMode );
