org.kuali.rice.kns.util
Class JstlPropertyHolder

java.lang.Object
  org.kuali.rice.kns.util.JstlPropertyHolder

All Implemented Interfaces:: Map

Direct Known Subclasses:: ConfigProperties

public abstract class JstlPropertyHolder
extends Object
implements Map
extends Object
implements Map

This class implements the Map interface for a Properties instance. Exports all properties from the given Properties instance as constants, usable from jstl. Implements the Map interface (by delegating everything to the PropertyTree, which really implements the Map methods directly) so that jstl can translate ${Constants.a} into a call to ConfigConstants.get( "a" ).

The contents of this Map cannot be changed once it has been initialized. Any calls to any of the Map methods made before the propertyTree has been initialized (i.e. before setProperties has been called) will throw an IllegalStateException.

Jstl converts ${Constants.a.b.c} into get("a").get("b").get("c"), so the properties are stored in a PropertyTree, which converts the initial set( "a.b.c", "value" ) into construction of the necessary tree structure to support get("a").get("b").get("c").

Implicitly relies on the assumption that the JSP will be calling toString() on the result of the final get, since get can only return one type, and that type must be the complex one so that further dereferencing will be possible.
