      • 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:

      • 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

        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.
