QueryNode with a reference to it's parent. |
Modifier and Type | Method and Description |
---|---|
abstract Object |
accept(QueryNodeVisitor visitor,
Object data)
Accepts a
QueryNodeVisitor and calls the appropriate visit
method on the visitor depending on the concrete implementation of
this QueryNode . |
String |
dump()
Dumps this QueryNode and its child nodes to a String.
|
abstract boolean |
equals(Object obj)
Returns
true if obj is the same type of
QueryNode as this node and is equal to
this node. |
QueryNode |
getParent()
Returns the parent
QueryNode or null if this is
the root node of a query tree. |
abstract int |
getType()
Returns the type of this query node.
|
abstract boolean |
needsSystemTree()
Returns
true if this query node needs items under
/jcr:system to be queried. |
