public NamespaceSupport()
Creates a new instance of NamespaceSupport.
| Method Detail | 
public void reset()
Resets the NamespaceSupport's state for reuse.
public void declarePrefix(java.lang.String pPrefix,
                          java.lang.String pURI)
Declares a new prefix.
public void undeclarePrefix(java.lang.String pPrefix)
Removes a prefix declaration. Assumes that the prefix is the current prefix. If not, throws a IllegalStateException.
public java.lang.String getNamespaceURI(java.lang.String pPrefix)
Given a prefix, returns the URI to which the prefix is currently mapped or null, if there is no such mapping.
Note: This methods behaviour is precisely
 defined by NamespaceContext.getNamespaceURI(java.lang.String).
getNamespaceURI in interface NamespaceContextpPrefix - The prefix in question
public java.lang.String getPrefix(java.lang.String pURI)
Returns a prefix currently mapped to the given URI or
 null, if there is no such mapping. This method may be used
 to find a possible prefix for an elements namespace URI. For
 attributes you should use getAttributePrefix(String).
Note: This methods behaviour is precisely
 defined by NamespaceContext.getPrefix(java.lang.String).
getPrefix in interface NamespaceContextpURI - The namespace URI in question
java.lang.IllegalArgumentException - The namespace URI is null.public java.lang.String getAttributePrefix(java.lang.String pURI)
Returns a non-empty prefix currently mapped to the given
 URL or null, if there is no such mapping. This method may be
 used to find a possible prefix for an attributes namespace
 URI. For elements you should use getPrefix(String).
pURI - Thhe namespace URI in question
java.lang.IllegalArgumentException - The namespace URI is null.public java.util.Iterator getPrefixes(java.lang.String pURI)
Returns a collection to all prefixes bound to the given namespace URI.
Note: This methods behaviour is precisely
 defined by NamespaceContext.getPrefixes(java.lang.String).
getPrefixes in interface NamespaceContextpURI - The namespace prefix in question
Iterator: Using it's
   Iterator.remove() method throws an
   UnsupportedOperationException.public boolean isPrefixDeclared(java.lang.String pPrefix)
Returns whether a given prefix is currently declared.
public int getContext()
ContentHandler.startElement(String, String, String, org.xml.sax.Attributes).
 The return value is used as a saveable state. After
 invoking 
 ContentHandler.endElement(String, String, String),
 the state is restored by calling checkContext(int).
public java.lang.String checkContext(int i)
getContext().
   NamespaceSupport nss;
   ContentHandler h;
   int context = nss.getContext();
   h.startElement("foo", "bar", "f:bar", new AttributesImpl());
   ...
   h.endElement("foo", "bar", "f:bar");
   for (;;) {
     String prefix = nss.checkContext(context);
     if (prefix == null) {
       break;
     }
     h.endPrefixMapping(prefix);
   }
