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
