All Implemented Interfaces:

IPropertyResolver

public class FallbackResolver
extends Object
implements IPropertyResolver

A FallbackResolver is a resolver, usually placed at the end of a chain of resolver and that will provide a default value for any given expression. This permits to have a little less strict resolution process (the substitution engine throwing exceptions if the resolver cannot give a non-null value)
