        Overrides:
        createHashCode in class Namespace
        Returns:
        the hash code based on the qualified name and the URI of the namespace and the hashCode() of the parent element.

      • equals

        public boolean equals​(Object object)
        Implements an identity based comparsion using the parent element as well as the prefix and URI
        Overrides:
        equals in class Namespace
        Parameters:
        object - DOCUMENT ME!
        Returns:
        DOCUMENT ME!

      • hashCode

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

      • getParent

        public Element getParent()
        Description copied from interface: Node

        getParent returns the parent Element if this node supports the parent relationship or null if it is the root element or does not support the parent relationship.

        This method is an optional feature and may not be supported for all Node implementations.

        Specified by:
        getParent in interface Node
        Overrides:
        getParent in class AbstractNode
        Returns:
        the parent of this node or null if it is the root of the tree or the parent relationship is not supported.

      • setParent

        public void setParent​(Element parent)
        Description copied from interface: Node

        setParent sets the parent relationship of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.

        This method should only be called from inside an Element implementation method and is not intended for general use.

        Specified by:
        setParent in interface Node
        Overrides:
        setParent in class AbstractNode
        Parameters:
        parent - is the new parent of this node.

      • supportsParent

        public boolean supportsParent()
        Description copied from interface: Node

        supportsParent returns true if this node supports the parent relationship.

        Some XML tree implementations are singly linked and only support downward navigation through children relationships. The default case is that both parent and children relationships are supported though for memory and performance reasons the parent relationship may not be supported.

        Specified by:
        supportsParent in interface Node
        Overrides:
        supportsParent in class AbstractNode
        Returns:
        true if this node supports the parent relationship or false it is not supported

      • isReadOnly

        public boolean isReadOnly()
        Description copied from interface: Node

        isReadOnly returns true if this node is read only and cannot be modified. Any attempt to modify a read-only Node will result in an UnsupportedOperationException being thrown.

        Specified by:
        isReadOnly in interface Node
        Overrides:
        isReadOnly in class AbstractNode
        Returns:
        true if this Node is read only and cannot be modified otherwise false.
