hasFeature

public boolean hasFeature(String feature,
                          String version)

Test if the DOM implementation implements a specific feature.

                         String version)

This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in .

Specified by:

getFeature in interface DOMImplementation

Parameters:

feature - The name of the feature requested.

version - This is the version number of the feature to test.

Returns:

Always returns null in this implementation
