java.lang.Object

org.openxml.dom.DOMImpl

All Implemented Interfaces:

DOMImplementation

Direct Known Subclasses:

HTMLDOMImpl

public class DOMImpl
extends Object
implements DOMImplementation

Provides number of methods for performing operations that are independent of any particular instance of the document object model. This class is unconstructable, the only way to obtain an instance of a DOM implementation is by calling the static method getDOMImplementation().

Method Detail

hasFeature

public final boolean hasFeature(String feature,
                                String version)

Return true if certain feature for specific DOM version supported by this implementation. Currently supports DOM Level 1 and 2, HTML, Traversal and Views.

Specified by:

hasFeature in interface DOMImplementation

Parameters:

feature - Name of feature to check

version - Optional version number

Returns:

True if supported

createDocumentType

public final DocumentType createDocumentType(String qualifiedName,
                                             String publicId,
                                             String systemId)

Creates an empty document type. The document type has qualified name, public and system identifiers, but no entities or notations.

Specified by:

createDocumentType in interface DOMImplementation

Parameters:

qualifiedName - The name of the document type to be created

publicId - The document type public identifier

systemId - The document type system identifier

Returns:

A new document type

createDocumentType

public DocumentType createDocumentType(String qualifiedName,
                                       String publicId,
                                       String systemId,
                                       String internalSubset)

createDocument

public final Document createDocument(String namespaceURI,
                                     String qualifiedName,
                                     DocumentType docType)
                              throws DOMException

Create a new document of the specified type with its document element.

Specified by:

createDocument in interface DOMImplementation

Parameters:

namespaceURI - The namespace URI of the document, or null

qualifiedName - The qualified name of the document element

docType - The type of the document, or null

Returns:

New document

Throws:

DOMException - The document type is already used, or the qualified name is invalid

getDOMImplementation

public static DOMImplementation getDOMImplementation()

Returns an instance of a DOMImplementation that can be used to perform operations that are not specific to a particular document instance, e.g. to create a new document.

Returns:

Reference to a valid DOM implementation

getFeature

public Object getFeature(String feature,
                         String version)

Specified by:
