public abstract class NodeTest

extends Pattern

A NodeTest is a simple kind of pattern that enables a context-free test of whether a node has a particular name. There are five kinds of name test: a full name test, a prefix test, and an "any node of a given type" test, an "any node of any type" test, and a "no nodes" test (used, e.g. for "@comment()")

Method Detail

matches

public abstract boolean matches(NodeInfo node)

Test whether this node test is satisfied by a given node

matches

public abstract boolean matches(short nodeType,
                                int fingerprint)

Test whether this node test is satisfied by a given node

Parameters:

nodeType - The type of node to be matched

fingerprint - identifies the expanded name of the node to be matched. The value should be -1 for a node with no name.

matches

public final boolean matches(NodeInfo node,
                             Context c)

Test whether this node test is satisfied by a given node, in a given Context

Specified by:

matches in class Pattern

Parameters:

node - The NodeInfo representing the Element or other node to be tested against the Pattern

c - The context in which the match is to take place. Only relevant if the pattern uses variables.

Returns:

true if the node matches the Pattern, false otherwise
