Method Detail

getURIForPrefix

public java.lang.String getURIForPrefix(java.lang.String prefix,
                                        boolean useDefault)

Parameters:

prefix - the namespace prefix

useDefault - true if the default namespace is to be used when the prefix is ""

Returns:

the uri for the namespace, or null if the prefix is not in scope

getFingerprint

public int getFingerprint(java.lang.String qname,
                          boolean useDefault,
                          NamePool pool)
                   throws XPathException

Use this NamespaceContext to resolve a lexical QName

Parameters:

qname - the lexical QName; this must have already been lexically validated

useDefault - true if the default namespace is to be used to resolve an unprefixed QName

pool - the NamePool to be used

Returns:

the integer fingerprint that uniquely identifies this name
