Examples of ChildNodeJoinCondition

javax.jcr.query.qom.ChildNodeJoinCondition
org.apache.jackrabbit.core.query.jsr283.qom.ChildNodeJoinCondition
Tests whether the {@link #getChildSelectorName childSelector} node is a childof the {@link #getParentSelectorName parentSelector} node. A node-tuplesatisfies the constraint only if:
```
  childSelectorNode.getParent().isSame(parentSelectorNode)
```
would return true, where childSelectorNode is the node for {@link #getChildSelectorName childSelector} and parentSelectorNodeis the node for {@link #getParentSelectorName parentSelector}.
The query is invalid if:
- {@link #getChildSelectorName childSelector} is not the name of aselector in the query, or
- {@link #getParentSelectorName parentSelector} is not the name of aselector in the query, or
- {@link #getChildSelectorName childSelector} is the same as{@link #getParentSelectorName parentSelector}.

org.jboss.dna.graph.query.model.ChildNodeJoinCondition
A join condition that evaluates to true only when the named child node is indeed a child of the named parent node.
