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()")- Author:

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 matchedfingerprint
- 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 classPattern
- Parameters:
node
- The NodeInfo representing the Element or other node to be tested against the Patternc
- 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
