visitWith
Description copied from class:Node
Visit a Node and dispatch on it to the appropriate method from the NodeVisitorv
. -
equals
Description copied from class:Node
Nodes only equal other Nodes that have equal labels. -
sameValueAs
Test that two nodes are semantically equivalent. In some cases this may be the same as equals, in others equals is stricter. For example, two xsd:int literals with the same value but different language tag are semantically equivalent but distinguished by the java equality function in order to support round tripping.Default implementation is to use equals, subclasses should override this.

-
matches
Description copied from class:Node
Answer true iff this node accepts the other one as a match. The default is an equality test; it is over-ridden in subclasses to provide the appropriate semantics for literals, ANY, and variables.
