package org.apache.tapestry.bean;
A helper bean to assist with providing defaults for unspecified parameters. It is initalized with an org.apache.tapestry.IBinding and a default value. It's value property is either the value of the binding, but if the binding is null, or the binding returns null, the default value is returned.

Returns the value of the binding. However, if the binding is null, or the binding returns null, then the defaultValue is returned instead.

        if ( == null)
            return ;
        Object value = .getObject();
        if (value == null)
            return ;
        return value;
