DOMImplementationSource

  • The DOMImplementationSource interface allows developers to access one or more DOM implementations based on desired features and versions.

  • It provides two key methods: getDOMImplementation to retrieve the first matching implementation and getDOMImplementationList to retrieve a list of all matching implementations.

  • Feature specifications are provided as strings, listing the feature name and optionally a version number, such as "XML 3.0 Traversal +Events 2.0".

  • If no matching implementation is found, the methods will return null or an empty list.
public interface DOMImplementationSource

This interface permits a DOM implementer to supply one or more implementations, based upon requested features and versions, as specified in . Each implemented DOMImplementationSource object is listed in the binding-specific list of available sources so that its DOMImplementation objects are made available.

See also the Document Object Model (DOM) Level 3 Core Specification.

Public Method Summary

abstract DOMImplementation
getDOMImplementation(String features)
A method to request the first DOM implementation that supports the specified features.
abstract DOMImplementationList
getDOMImplementationList(String features)
A method to request a list of DOM implementations that support the specified features and versions, as specified in .

Public Methods

public abstract DOMImplementation getDOMImplementation (String features)

A method to request the first DOM implementation that supports the specified features.

Parameters
features A string that specifies which features and versions 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 method returns the first item of the list returned by getDOMImplementationList. As an example, the string "XML 3.0 Traversal +Events 2.0" will request a DOM implementation that supports the module "XML" for its 3.0 version, a module that support of the "Traversal" module for any version, and the module "Events" for its 2.0 version. The module "Events" must be accessible using the method Node.getFeature() and DOMImplementation.getFeature().
Returns
  • The first DOM implementation that support the desired features, or null if this source has none.

public abstract DOMImplementationList getDOMImplementationList (String features)

A method to request a list of DOM implementations that support the specified features and versions, as specified in .

Parameters
features A string that specifies which features and versions 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 3.0 Traversal +Events 2.0"
Returns
  • A list of DOM implementations that support the desired features.
