Class DummyNamespaceResolver

    java.lang.Object
      net.sf.saxon.instruct.DummyNamespaceResolver

All Implemented Interfaces:
  java.io.Serializable, NamespaceResolver

    public final class DummyNamespaceResolver

extends java.lang.Object
implements java.io.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.

`java.lang.String` `getURIForPrefix(java.lang.String prefix, boolean useDefault)` Get the namespace URI corresponding to a given prefix.
