Interface DOMImplementationSource

    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.

Since:
  DOM Level 3

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

Method Detail

### getDOMImplementation

    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.

### getDOMImplementationList

    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.
