public class LeafConstraintsTag
extends ContextReferrerTag
implements NodeQueryContainer, QueryContainerReferrer

Sub-tag of tree container. Is itself a Query container. It makes it possible to set the 'search constraints on a tree'. Search constraints do not change the actual tree, but only the 'leaves'. So, it is kind of constraint only valid on the leaves. This makes it possible to easily search through a tree of objects.
