Class DummyNamespaceResolver

java.lang.Object
  extended by net.sf.saxon.expr.instruct.DummyNamespaceResolver
All Implemented Interfaces:
Serializable, NamespaceResolver

public final class DummyNamespaceResolver
extends Object
implements Serializable, 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.

public String getURIForPrefix(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 Iterator<String> iteratePrefixes()

Specified by:
iteratePrefixes in interface NamespaceResolver
Returns:
