public final class

DOMImplementationRegistry

extends Object
java.lang.Object
   ↳ org.w3c.dom.bootstrap.DOMImplementationRegistry

Class Overview

A factory that enables applications to obtain instances of DOMImplementation.

Example: 

  // get an instance of the DOMImplementation registry
  DOMImplementationRegistry registry =
       DOMImplementationRegistry.newInstance();
  // get a DOM implementation the Level 3 XML module
  DOMImplementation domImpl =
       registry.getDOMImplementation("XML 3.0");

This provides an application with an implementation-independent starting point. DOM implementations may modify this class to meet new security standards or to provide *additional* fallbacks for the list of DOMImplementationSources.

Constants

public static final String PROPERTY

The system property to specify the DOMImplementationSource class names.

Constant Value: "org.w3c.dom.DOMImplementationSourceList"

Public Methods

public void addSource (DOMImplementationSource s)

Register an implementation.

Parameters
s The source to be registered, may not be null

public DOMImplementation getDOMImplementation (String features)

Return the first implementation that has the desired features, or null if none is found.

Parameters
features A string that specifies which features are required. This is a space separated list in which each feature is specified by its name optionally followed by a space and a version number. This is something like: "XML 1.0 Traversal +Events 2.0"
Returns
  • An implementation that has the desired features, or null if none found.

public DOMImplementationList getDOMImplementationList (String features)

Return a list of implementations that support the desired features.

Parameters
features A string that specifies which features are required. This is a space separated list in which each feature is specified by its name optionally followed by a space and a version number. This is something like: "XML 1.0 Traversal +Events 2.0"
Returns
  • A list of DOMImplementations that support the desired features.

public static DOMImplementationRegistry newInstance ()

Obtain a new instance of a DOMImplementationRegistry. The DOMImplementationRegistry is initialized by the application or the implementation, depending on the context, by first checking the value of the Java system property org.w3c.dom.DOMImplementationSourceList and the service provider whose contents are at "META_INF/services/org.w3c.dom.DOMImplementationSourceList". The value of this property is a white-space separated list of names of availables classes implementing the DOMImplementationSource interface. Each class listed in the class name list is instantiated and any exceptions encountered are thrown to the application.

Returns
  • an initialized instance of DOMImplementationRegistry
Throws
ClassNotFoundException If any specified class can not be found
InstantiationException If any specified class is an interface or abstract class
IllegalAccessException If the default constructor of a specified class is not accessible
ClassCastException If any specified class does not implement DOMImplementationSource
