org.apache.tapestry.IBinding
A binding is the mechanism used to provide values for parameters of specific {@link IComponent} instances. The component doesn'tcare where the required value comes from, it simply requires that a value be provided when needed.
Bindings are set inside the containing component's specification. Bindings may be static or dynamic (though that is irrelevant to the component). Components may also use a binding to write a value back through a property to some other object (typically, another component). @author Howard Lewis Ship @version $Id: IBinding.java 243791 2004-02-19 17:38:13Z hlship $
