clone()
Returns a (deep) clone of this query model node.

equals(Object other)
Returns true if this query model node and its children are recursively equal to o and its
children.

getAssuredBindingNames()
Gets the names of the bindings that are guaranteed to be present in the results produced by this tuple
expression.
|
Set<String> |
