Class DummyNamespaceResolver

java.lang.Object

net.sf.saxon.expr.instruct.DummyNamespaceResolver

All Implemented Interfaces:

NamespaceResolver

public final class DummyNamespaceResolver
extends java.lang.Object
implements NamespaceResolver

A dummy namespace resolver used when validating QName-valued attributes written to the result tree. The namespace node might be created after the initial validation of the attribute, so in the first round of validation we only check the lexical form of the value, and we defer prefix checks until later.

Method Summary

Modifier and Type	Method and Description
static DummyNamespaceResolver	getInstance() Return the singular instance of this class
java.lang.String	getURIForPrefix(java.lang.String prefix, boolean useDefault) Get the namespace URI corresponding to a given prefix.
java.util.Iterator<java.lang.String>	iteratePrefixes() Get an iterator over all the prefixes declared in this namespace context.

Method Detail

getInstance

public static DummyNamespaceResolver getInstance()

Return the singular instance of this class

Returns:

the singular instance

getURIForPrefix

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

Get the namespace URI corresponding to a given prefix.

Specified by:

getURIForPrefix in interface NamespaceResolver

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

iteratePrefixes

public java.util.Iterator<java.lang.String> iteratePrefixes()

Get an iterator over all the prefixes declared in this namespace context. This will include the default namespace (prefix="") and the XML namespace where appropriate

Specified by:

iteratePrefixes in interface NamespaceResolver

Returns:

an iterator over all the prefixes for which a namespace binding exists, including the zero-length string to represent the null/absent prefix if it is bound
