All Implemented Interfaces:

NodeTest

public class UnionNodeTest

extends java.lang.Object

implements NodeTest

Logical OR of two NodeTests.

Field Summary

NodeTest	t1
NodeTest	t2

Constructor Summary

UnionNodeTest(NodeTest t1, NodeTest t2)

Method Summary

boolean	accepts(int nodeKind, QName nodeName) Optimized test method.
boolean	accepts(Node node) Generic test method.
int	getNodeKind() Returns the node kind (Node.ELEMENT, Node.TEXT etc) specifically matched, or -1 if several kinds can be matched.
boolean	needsNode() Tells whether more information than the node kind and its name are necessary to perform the test.
boolean	staticallyCheckable() Returns true for simple node test (node kind only).

Method Detail

toString

public java.lang.String toString()

getNodeKind

public int getNodeKind()

Description copied from interface: NodeTest

Returns the node kind (Node.ELEMENT, Node.TEXT etc) specifically matched, or -1 if several kinds can be matched.

Specified by:

getNodeKind in interface NodeTest

staticallyCheckable

public boolean staticallyCheckable()

Description copied from interface: NodeTest

Returns true for simple node test (node kind only).

Specified by:

staticallyCheckable in interface NodeTest

accepts

public boolean accepts(int nodeKind,
                       QName nodeName)

Description copied from interface: NodeTest

Optimized test method. Can be used if only the node-kind and its name are necessary. This condition can be tested with method NodeTest.needsNode().

Specified by:

accepts in interface NodeTest

Returns:

true if node matched. A null name is always accepted.

needsNode

public boolean needsNode()

Description copied from interface: NodeTest

Tells whether more information than the node kind and its name are necessary to perform the test.

Specified by:

needsNode in interface NodeTest

Returns:

true if the node itself is necessary for checking (not only the kind and name). Allows optimization (avoids building a Node just for testing). Returns true for extended tests like DocumentTest.

accepts

public boolean accepts(Node node)

Description copied from interface: NodeTest

Generic test method.

Specified by:

accepts in interface NodeTest

Returns:

true if node matched. Used for extended tests like DocumentTest.
