Class PropertiesSupportHelper

java.lang.Object

org.gvsig.tools.util.PropertiesSupportHelper

All Implemented Interfaces:

java.lang.Cloneable, Observable, Persistent, PropertiesSupport

Direct Known Subclasses:

ExtendedPropertiesHelper

public class PropertiesSupportHelper
extends java.lang.Object
implements PropertiesSupport, Persistent, Observable, Cloneable

This class is intended to serve as an aid to the implementation of PropertiesSupport. When we have a class that implements the PropertiesSupport interface, we will use PropertiesSupportHelper to implement it. For this, we will declare a property "propertiesHelper", and we will implement the interface methods delegating in it. private PropertiesSupportHelper propertiesHelper = new PropertiesSupportHelper(); ...

public PropertiesSupportHelper clone()
                              throws java.lang.CloneNotSupportedException

Description copied from interface: Cloneable

Creates a copy of the object.

Overrides:

clone in class java.lang.Object

Returns:

a copy of the object

Throws:

java.lang.CloneNotSupportedException - if the instance of the object cannot be cloned. As this is extending Cloneable so its sure it implements it, so this exception may be used for problems on specific object instances.
