Interface ChildNodeJoinCondition

All Superinterfaces:

JoinCondition

All Known Implementing Classes:

ChildNodeJoinConditionImpl

public interface ChildNodeJoinCondition
extends JoinCondition

Tests whether the childSelector node is a child of the parentSelector node. A node-tuple satisfies the constraint only if:

  childSelectorNode.getParent().isSame(parentSelectorNode)

would return true, where childSelectorNode is the node for childSelector and parentSelectorNode is the node for parentSelector.

The query is invalid if:

• childSelector is not the name of a selector in the query, or
• parentSelector is not the name of a selector in the query, or
• childSelector is the same as parentSelector.

JCR 2.0
