Constructor Detail

NoNodeTest

public NoNodeTest()
Method Detail

getInstance

public static NoNodeTest getInstance()
Get a NoNodeTest instance


getNodeType

public final short getNodeType()
Description copied from class: Pattern
Determine the types of nodes to which this pattern applies. Used for optimisation. For patterns that match nodes of several types, return NodeInfo.NODE

Overrides:
getNodeType in class Pattern
Returns:
the type of node matched by this pattern. e.g. NodeInfo.ELEMENT or NodeInfo.TEXT

matches

public final boolean matches(NodeInfo node)
Test whether this node test is satisfied by a given node

Specified by:
matches in class NodeTest

matches

public boolean matches(short nodeType,
                       int fingerprint)
Test whether this node test is satisfied by a given node

Specified by:
matches in class NodeTest
Parameters:
nodeType - The type of node to be matched
fingerprint - identifies the expanded name of the node to be matched

getDefaultPriority

public final double getDefaultPriority()
Determine the default priority of this node test when used on its own as a Pattern

Overrides:
getDefaultPriority in class Pattern
