## com.icl.saxon.pattern
Class NodeTest

    java.lang.Object
      com.icl.saxon.pattern.Pattern
          com.icl.saxon.pattern.NodeTest

Direct Known Subclasses:
  AnyChildNodePattern, AnyNodeTest, NamespaceTest, NameTest, NodeTypeTest, NoNodeTest

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()")

Constructor Detail

### NodeTest

    public NodeTest()

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
