      • setNamespaceContext

        public void setNamespaceContext​(NamespaceContext context)
      • setSymbolTable

        public void setSymbolTable​(SymbolTable symbolTable)
      • setDeclaredPrefixes

        public void setDeclaredPrefixes​(List prefixes)
      • getDeclaredPrefixes

        public List getDeclaredPrefixes()
      • getURI

        public String getURI​(String prefix)
        Description copied from interface: 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 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: 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 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.

        NamespaceContext.getPrefix(java.lang.String)
      • getAllPrefixes

        public Enumeration getAllPrefixes()
        Description copied from interface: 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 NamespaceContext
        Returns:
        Enumeration
      • pushContext

        public void pushContext()
        Description copied from interface: 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 NamespaceContext
        See Also:
        NamespaceContext.popContext()
      • popContext

        public void popContext()
        Description copied from interface: 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 NamespaceContext

        NamespaceContext.pushContext()
      • declarePrefix

        public boolean declarePrefix​(String prefix,
                                     String uri)
        Description copied from interface: 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 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

      • reset

        public void reset()
        Description copied from interface: 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.
