Examples of DescendantNode

javax.jcr.query.qom.DescendantNode
org.apache.jackrabbit.core.query.jsr283.qom.DescendantNode
Tests whether the {@link #getSelectorName selector} node is a descendantof a node reachable by absolute path {@link #getPath path}.
A node-tuple satisfies the constraint only if:
```
  selectorNode.getAncestor(n).isSame(session.getNode(path)) && selectorNode.getDepth() > n
```
would return true for some non-negative integer n, where {@link #getSelectorName selectorNode} is the node for the specifiedselector.
The query is invalid if:
- {@link #getSelectorName selector} is not the name of a selector in thequery, or
- {@link #getPath path} is not a syntactically valid absolute path. Note,however, that if the path is syntactically valid but does not identify a node in the repository (or the node is not visible to this session, because of access control constraints), the query is valid but the constraint is not satisfied.
