public final class DOMImplementationRegistry extends Object
A factory that enables applications to obtain instances ofDOMImplementation.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.
- Since:
- 1.5, DOM Level 3

Method Detail
newInstance
public static DOMImplementationRegistry newInstance() throws ClassNotFoundException, InstantiationException, IllegalAccessException, ClassCastException
Obtain a new instance of aDOMImplementationRegistry. TheDOMImplementationRegistryis initialized by the application or the implementation, depending on the context, by first checking the value of the Java system propertyorg.w3c.dom.DOMImplementationSourceListand 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 theDOMImplementationSourceinterface. 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 foundInstantiationException- If any specified class is an interface or abstract classIllegalAccessException- If the default constructor of a specified class is not accessibleClassCastException- If any specified class does not implementDOMImplementationSource
getDOMImplementation
public DOMImplementation getDOMImplementation(String features)
Return the first implementation that has the desired features, ornullif 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
nullif none found.
getDOMImplementationList
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.
addSource
public void addSource(DOMImplementationSource s)
Register an implementation.- Parameters:
s- The source to be registered, may not benull
