public class ConstraintTag

extends org.apache.commons.jelly.DynaBeanTagSupport

This class represents a layout-manager constraints as passed in the second argument of Container#add(Component,Object).

In essence, it looks really like nothing else than a bean-class... with getConstraintObject(). Probably a shorter java-source is do-able.

TODO: this class should probably be extended with special treatment for dimensios using the converter package.
