Interface DescendantNodeJoinCondition

All Superinterfaces:
JoinCondition
All Known Implementing Classes:
DescendantNodeJoinConditionImpl
public interface DescendantNodeJoinCondition extends JoinCondition
Tests whether the descendantSelector node is a descendant of the ancestorSelector node. A node-tuple satisfies the constraint only if: 
  descendantSelectorNode.getAncestor(n).isSame(ancestorSelectorNode) invalid input: '&'invalid input: '&'
     descendantSelectorNode.getDepth() > n
would return true some some non-negative integer n, where descendantSelectorNode is the node for descendantSelector and ancestorSelectorNode is the node for ancestorSelector.
