org.apache.xpath.domapi
Class XPathNamespaceImpl

java.lang.Object
  org.apache.xpath.domapi.XPathNamespaceImpl

All Implemented Interfaces:: org.w3c.dom.Node, org.w3c.dom.xpath.XPathNamespace

public class XPathNamespaceImpl
extends java.lang.Object
implements org.w3c.dom.xpath.XPathNamespace

The XPathNamespace interface is returned by XPathResult interfaces to represent the XPath namespace node type that DOM lacks. There is no public constructor for this node type. Attempts to place it into a hierarchy or a NamedNodeMap result in a DOMException with the code HIERARCHY_REQUEST_ERR . This node is read only, so methods or setting of attributes that would mutate the node result in a DOMException with the code NO_MODIFICATION_ALLOWED_ERR.

The core specification describes attributes of the Node interface that are different for different node node types but does not describe XPATH_NAMESPACE_NODE, so here is a description of those attributes for this node type. All attributes of Node not described in this section have a null or false value.

ownerDocument matches the ownerDocument of the ownerElement even if the element is later adopted.

prefix is the prefix of the namespace represented by the node.

nodeName is the same as prefix.

nodeType is equal to XPATH_NAMESPACE_NODE.

namespaceURI is the namespace URI of the namespace represented by the node.

adoptNode, cloneNode, and importNode fail on this node type by raising a DOMException with the code NOT_SUPPORTED_ERR.In future versions of the XPath specification, the definition of a namespace node may be changed incomatibly, in which case incompatible changes to field values may be required to implement versions beyond XPath 1.0.

See also the Document Object Model (DOM) Level 3 XPath Specification. This implementation wraps the DOM attribute node that contained the namespace declaration.

Constructor Summary

XPathNamespaceImpl(org.w3c.dom.Node node)
          Constructor for XPathNamespaceImpl.

Method Summary

org.w3c.dom.Node appendChild(org.w3c.dom.Node arg0)
          Adds the node newChild to the end of the list of children of this node.

org.w3c.dom.Node cloneNode(boolean arg0)
          Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes.

org.w3c.dom.NamedNodeMap getAttributes()
          A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.

org.w3c.dom.NodeList getChildNodes()
          A NodeList that contains all children of this node.

org.w3c.dom.Node getFirstChild()
          The first child of this node.

org.w3c.dom.Node getLastChild()
          The last child of this node.

java.lang.String getLocalName()
          Returns the local part of the qualified name of this node.

java.lang.String getNamespaceURI()
          The namespace URI of this node, or null if it is unspecified (see ).

org.w3c.dom.Node getNextSibling()
          The node immediately following this node.

java.lang.String getNodeName()
          The name of this node, depending on its type; see the table above.

short getNodeType()
          A code representing the type of the underlying object, as defined above.

java.lang.String getNodeValue()
          The value of this node, depending on its type; see the table above.

org.w3c.dom.Document getOwnerDocument()
          The Document object associated with this node.

org.w3c.dom.Element getOwnerElement()
          The Element on which the namespace was in scope when it was requested.

org.w3c.dom.Node getParentNode()
          The parent of this node.

java.lang.String getPrefix()
          The namespace prefix of this node, or null if it is unspecified.

org.w3c.dom.Node getPreviousSibling()
          The node immediately preceding this node.

boolean hasAttributes()
          Returns whether this node (if it is an element) has any attributes.

boolean hasChildNodes()
          Returns whether this node has any children.

org.w3c.dom.Node insertBefore(org.w3c.dom.Node arg0, org.w3c.dom.Node arg1)
          Inserts the node newChild before the existing child node refChild.

boolean isSupported(java.lang.String arg0, java.lang.String arg1)
          Tests whether the DOM implementation implements a specific feature and that feature is supported by this node, as specified in .

void normalize()
          Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.

org.w3c.dom.Node removeChild(org.w3c.dom.Node arg0)
          Removes the child node indicated by oldChild from the list of children, and returns it.

org.w3c.dom.Node replaceChild(org.w3c.dom.Node arg0, org.w3c.dom.Node arg1)
          Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.

void setNodeValue(java.lang.String arg0)
          The value of this node, depending on its type; see the table above.

void setPrefix(java.lang.String arg0)
          The namespace prefix of this node, or null if it is unspecified.

XPathNamespaceImpl

public XPathNamespaceImpl(org.w3c.dom.Node node)

Constructor for XPathNamespaceImpl.

Method Detail

getOwnerElement

public org.w3c.dom.Element getOwnerElement()

Description copied from interface: org.w3c.dom.xpath.XPathNamespace

The Element on which the namespace was in scope when it was requested. This does not change on a returned namespace node even if the document changes such that the namespace goes out of scope on that element and this node is no longer found there by XPath.

Specified by:: getOwnerElement in interface org.w3c.dom.xpath.XPathNamespace
