    • get

      public static Namespace get(String prefix, String uri)
      A helper method to return the Namespace instance for the given prefix and URI
      Parameters:
      prefix - DOCUMENT ME!

      Returns:
      an interned Namespace object

    • getNodeType

      public short getNodeType()
      Description copied from interface: Node
      Returns the code according to the type of node. This makes processing nodes polymorphically much easier as the switch statement can be used instead of multiple if (instanceof) statements.
      Specified by:
      getNodeType in interface Node
      Overrides:
      getNodeType in class AbstractNode
      Returns:
      a W3C DOM complient code for the node type such as ELEMENT_NODE or ATTRIBUTE_NODE

    • hashCode

      public int hashCode()
      DOCUMENT ME!
      Overrides:
      hashCode in class Object
      Returns:
      the hash code based on the qualified name and the URI of the namespace.

    • createHashCode

      protected int createHashCode()
      Factory method to create the hashcode allowing derived classes to change the behaviour
      Returns:
      DOCUMENT ME!

    • equals

      public boolean equals(Object object)
      Checks whether this Namespace equals the given Namespace. Two Namespaces are equals if their URI and prefix are equal.
      Overrides:
      equals in class Object
      Parameters:
      object - DOCUMENT ME!
      Returns:
      DOCUMENT ME!

    • getText

      public String getText()
      Description copied from interface: Node

      Returns the text of this node.

      Specified by:
      getText in interface Node
      Overrides:
      getText in class AbstractNode
      Returns:
      the text for this node.

    • getStringValue

      public String getStringValue()
      Description copied from interface: Node
      Returns the XPath string-value of this node. The behaviour of this method is defined in the XPath specification .
      Specified by:
      getStringValue in interface Node
      Overrides:
      getStringValue in class AbstractNode
      Returns:
      the text from all the child Text and Element nodes appended together.

    • getPrefix

      public String getPrefix()
      DOCUMENT ME!
      Returns:
      the prefix for this Namespace.

      the URI for this Namespace.

    • getXPathNameStep

      public String getXPathNameStep()

    • getPath

      public String getPath(Element context)
      Description copied from interface: Node
      Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c. No indexing will be used to restrict the path if multiple elements with the same name occur on the path.
      Parameters:
      context - is the parent context from which the relative path should start. If the context is null or the context is not an ancestor of this node then the path will be absolute and start from the document and so begin with the '/' character.
      Returns:
      the XPath expression relative to the given context which will return a nodeset containing at least this node.

    • getUniquePath

      public String getUniquePath(Element context)
      Description copied from interface: Node

      Returns the relative unique XPath expression from the given context which will return a nodeset of one node which is the current node. This method will use the XPath index operator to restrict the path if multiple elements with the same name occur on the path.

      Parameters:
      context - is the parent context from which the path should start. If the context is null or the context is not an ancestor of this node then the path will start from the document and so begin with the '/' character.
      Returns:
      the XPath expression relative to the given context which will return a nodeset containing just this node.
