All Implemented Interfaces:

extends Object
implements NamespaceResolver

This class is a NamespaceResolver that modifies an underyling NamespaceResolver by changing the mapping of the null prefix to be a specified namespace, rather than the one used by the underlying namespace resolver.

Constructor Summary
`NamespaceResolverWithDefault(NamespaceResolver base, String defaultNamespace)`

Method Summary
`String` `getURIForPrefix(String prefix, boolean useDefault)` Get the namespace URI corresponding to a given prefix.
`Iterator<String>` `iteratePrefixes()` Get an iterator over all the prefixes declared in this namespace context.

### NamespaceResolverWithDefault

    public NamespaceResolverWithDefault(NamespaceResolver base,
                                        String defaultNamespace)

Method Detail

### getURIForPrefix

    public String getURIForPrefix(String prefix,
                                  boolean useDefault)

  Get the namespace URI corresponding to a given prefix. Return null if the prefix is not in scope.

  Specified by:
    `getURIForPrefix` in interface `NamespaceResolver`
  Parameters:
    `prefix` - the namespace prefix. May be the zero-length string, indicating that there is no prefix. This indicates either the default namespace or the null namespace, depending on the value of useDefault.
    `useDefault` - true if the default namespace is to be used when the prefix is "". If false, the method returns "" when the prefix is "".
  Returns:
    the uri for the namespace, or null if the prefix is not in scope. The "null namespace" is represented by the pseudo-URI "".

### iteratePrefixes

    public Iterator<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`
