Interface DescendantNodeJoinCondition

All Superinterfaces:

JoinCondition

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) &&
     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.

Since:

JCR 2.0
