Class ERXProxyAssociation

java.lang.Object

com.webobjects.appserver.WOAssociation

er.extensions.appserver.ERXProxyAssociation

All Implemented Interfaces:

Cloneable

public class ERXProxyAssociation
extends WOAssociation
implements Cloneable

ERXProxyAssociation allows you to create a wrapper around an existing association for the purposes of injecting a prefix or a suffix to the association's value. This is useful in, for instance, dynamic elements where you want to guarantee that a particular CSS class is prepended to an existing "class" binding where you don't necessarily have easy access to the original "class" WOAssociation (like if you extend WOHyperlink, for example).
