Constructor Detail

NamespaceImpl

protected NamespaceImpl(DocumentImpl owner,
                        String prefix,
                        String uri)

Construct a namespace node instance.

Parameters:

prefix - The namespace declaration prefix. This is returned by getNodeName()

uri - The namespace uri. This is returned by getNodeValue()

Method Detail

getNodeType

public short getNodeType()

A code representing the type of the underlying object, as defined above.

Specified by:

getNodeType in interface Node

Specified by:

getNodeType in class NodeImpl

getParentNode

public Node getParentNode()

The parent of this node. All nodes, except Document, DocumentFragment, and Attr may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.

Specified by:

getParentNode in interface Node

Overrides:

getParentNode in class NodeImpl

getNodeValue

public String getNodeValue()
                    throws DOMException

The value of this node, depending on its type; see the table above.

Specified by:

getNodeValue in interface Node

Overrides:

getNodeValue in class NodeImpl

Throws:

DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

DOMException - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

setOwningElement

public void setOwningElement(Element parent)

Set the parent of this namespace node.

Parameters:

parent - The owning Element of this namespace node

getNamespaceName

public NamespaceName getNamespaceName()

Return the NamespaceName object for this namespace node. This should generally be used in preference to getNodeValue() (which returns the string value of the uri) because NamespaceName objects can be compared much more efficiently than can strings.

Specified by:

getNamespaceName in interface Namespace

Returns:

The NamespaceName of this namespace node

getBaseURI

public String getBaseURI()

Return the base URI string for this node. If the base URI has not been explicitly set for this node the base URI of the parent node is returned. This may return null if the base URI has not been set for any node in this nodes chain of ancestors.

Overrides:

getBaseURI in class NodeImpl

Returns:

The base URI string for this node, or null if no base URI has been set for this node or one of its ancestors.
