Constructor Detail

NamespaceTest

public NamespaceTest(NamePool pool,
                     int nodeType,
                     java.lang.String uri)
Method Detail

matches

public boolean matches(int nodeType,
                       int fingerprint,
                       int annotation)
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
annotation - The actual content type of the node

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

getNodeKind

public int getNodeKind()
Determine the types of nodes to which this pattern applies. Used for optimisation. For patterns that match nodes of several types, return Type.NODE

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

allowsTextNodes

public boolean allowsTextNodes()
Indicate whether this NodeTest is capable of matching text nodes

Specified by:
allowsTextNodes in class NodeTest

toString

public java.lang.String toString()
Description copied from interface: ItemType
Produce a representation of this type name for use in error messages. Where this is a QName, it will use conventional prefixes

Specified by:
toString in interface ItemType
Overrides:
toString in class Pattern
