Class NamespaceContextImpl

java.lang.Object
net.sf.saxon.xpath.NamespaceContextImpl
All Implemented Interfaces:
NamespaceContext, NamespaceResolver

public class NamespaceContextImpl extends Object implements NamespaceContext, NamespaceResolver
This class bridges between the JAXP 1.3 NamespaceContext interface and Saxon's equivalent NamespaceResolver interface. It allows any implementation of the Saxon NamespaceResolver to be wrapped as a JAXP NamespaceContext.

      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 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
    • getNamespaceURI

      public String getNamespaceURI(String prefix)

      getNamespaceURI in interface NamespaceContext
      Parameters:
      prefix - a namespace prefix
      Returns:
      the corresponding URI, if the prefix is bound, or "" otherwise
    • getPrefix
