Class ElementNSImpl

public class ElementNSImpl extends ElementImpl

ElementNSImpl inherits from ElementImpl and adds namespace support.

The qualified name is the node name, and we store localName which is also used in all queries. On the other hand we recompute the prefix when necessary.

Method Detail

getBaseURI

public String getBaseURI()
DOM Level 3 WD - Experimental. Retrieve baseURI

getLocalName

public String getLocalName()
Introduced in DOM Level 2.

Returns the local part of the qualified name of this node.

Since: WD-DOM-Level-2-19990923

getNamespaceURI

public String getNamespaceURI()
Introduced in DOM Level 2.

The namespace URI of this node, or null if it is unspecified.

This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Since: WD-DOM-Level-2-19990923

getPrefix

public String getPrefix()
Introduced in DOM Level 2.

The namespace prefix of this node, or null if it is unspecified.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Since: WD-DOM-Level-2-19990923

getTypeName

public String getTypeName()

See Also: org.w3c.dom.TypeInfo#getTypeName()

getTypeNamespace

public String getTypeNamespace()

See Also: org.w3c.dom.TypeInfo#getTypeNamespace()

isDerivedFrom

public boolean isDerivedFrom(String typeNamespaceArg, String typeNameArg, int derivationMethod)
Introduced in DOM Level 2.

Checks if a type is derived from another by restriction. See: http://www.w3.org/TR/DOM-Level-3-Core/core.html#TypeInfo-isDerivedFrom

Parameters: ancestorNS The namspace of the ancestor type declaration ancestorName The name of the ancestor type declaration type The reference type definition

Returns: boolean True if the type is derived by restriciton for the reference type

setPrefix

public void setPrefix(String prefix)
Introduced in DOM Level 2.

Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.

Parameters: prefix The namespace prefix of this node, or null(empty string) if it is unspecified.

Throws: INVALID_CHARACTER_ERR Raised if the specified prefix contains an invalid character. DOMException

Since: WD-DOM-Level-2-19990923

setType

public void setType(XSTypeDefinition type)
NON-DOM: setting type used by the DOM parser

See Also: NodeImpl

setValues

protected void setValues(CoreDocumentImpl ownerDocument, String namespaceURI, String qualifiedName, String localName)
NON-DOM: resets this node and sets specified values for the node

Parameters: ownerDocument namespaceURI qualifiedName localName
