public final class DOMImplementationRegistry extends Object
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.
Since: DOM Level 3

Method Summary | |
---|---|
void | addSource(DOMImplementationSource s)
Register an implementation.
|
DOMImplementation | getDOMImplementation(String features)
Return the first implementation that has the desired
features, or null if none is found.
|
DOMImplementationList | getDOMImplementationList(String features)
Return a list of implementations that support the
desired features.

static DOMImplementationRegistry | newInstance()

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