    • getURI

      public String getURI(String prefix)
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Look up a prefix and get the currently-mapped Namespace URI.

      This method looks up the prefix in the current context. If no mapping is found, this methods will continue lookup in the parent context(s). Use the empty string ("") for the default Namespace.

      Specified by:
      getURI in interface org.apache.xerces.xni.NamespaceContext
      Parameters:
      prefix - The prefix to look up.
      Returns:
      The associated Namespace URI, or null if the prefix is undeclared in this context.

    • getPrefix

      public String getPrefix(String uri)
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Look up a namespace URI and get one of the mapped prefix.

      This method looks up the namespace URI in the current context. If more than one prefix is currently mapped to the same URI, this method will make an arbitrary selection If no mapping is found, this methods will continue lookup in the parent context(s).

      Specified by:
      getPrefix in interface org.apache.xerces.xni.NamespaceContext
      Parameters:
      uri - The namespace URI to look up.
      Returns:
      One of the associated prefixes, or null if the uri does not map to any prefix.
      See Also:
      • NamespaceContext.getPrefix(java.lang.String)

    • getAllPrefixes

      public Enumeration getAllPrefixes()
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Return an enumeration of all prefixes whose declarations are active in the current context. This includes declarations from parent contexts that have not been overridden.
      Specified by:
      getAllPrefixes in interface org.apache.xerces.xni.NamespaceContext
      Returns:
      Enumeration

    • pushContext

      public void pushContext()
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Start a new Namespace context.

      A new context should be pushed at the beginning of each XML element: the new context will automatically inherit the declarations of its parent context, but it will also keep track of which declarations were made within this context.

      Specified by:
      pushContext in interface org.apache.xerces.xni.NamespaceContext
      See Also:
      • NamespaceContext.popContext()

    • popContext

      public void popContext()
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Revert to the previous Namespace context.

      The context should be popped at the end of each XML element. After popping the context, all Namespace prefix mappings that were previously in force are restored.

      Users must not attempt to declare additional Namespace prefixes after popping a context, unless you push another context first.

      Specified by:
      popContext in interface org.apache.xerces.xni.NamespaceContext
      See Also:
      • NamespaceContext.pushContext()

    • declarePrefix

      public boolean declarePrefix(String prefix, String uri)
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Declare a Namespace prefix.

      This method declares a prefix in the current Namespace context; the prefix will remain in force until this context is popped, unless it is shadowed in a descendant context.

      Note that to declare a default Namespace, use the empty string. The prefixes "xml" and "xmlns" can't be rebound.

      Note that you must not declare a prefix after you've pushed and popped another Namespace.

      Specified by:
      declarePrefix in interface org.apache.xerces.xni.NamespaceContext
      Parameters:
      prefix - The prefix to declare, or null for the empty string.
      uri - The Namespace URI to associate with the prefix.
      Returns:
      true if the prefix was legal, false otherwise

      • NamespaceContext.getURI(java.lang.String)
      • NamespaceContext.getDeclaredPrefixAt(int)

    • getDeclaredPrefixCount

      public int getDeclaredPrefixCount()
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Return a count of locally declared prefixes, including the default prefix if bound.
      Specified by:
      getDeclaredPrefixCount in interface org.apache.xerces.xni.NamespaceContext

    • getDeclaredPrefixAt

      public String getDeclaredPrefixAt(int index)
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Returns the prefix at the specified index in the current context.
      Specified by:
      getDeclaredPrefixAt in interface org.apache.xerces.xni.NamespaceContext

    • reset

      public void reset()
      Description copied from interface: org.apache.xerces.xni.NamespaceContext
      Reset this Namespace support object for reuse.

      It is necessary to invoke this method before reusing the Namespace support object for a new session.

      Note that implementations of this method need to ensure that the declaration of the prefixes "xmlns" and "xml" are available.

      reset in interface org.apache.xerces.xni.NamespaceContext
