Class EmptySource

  • All Implemented Interfaces:

    public class EmptySource
    extends java.lang.Object
    implements javax.xml.transform.Source
    This class is an implementation of the JAXP Source interface. It represents a dummy Source, which resolves to an empty sequence. A URIResolver (called perhaps in furtherance of the doc() or document() function) can choose to return an EmptySource for example if a URI is not accessible; the effect is that the call on doc() or document() returns an empty sequence. This may be useful to emulate the behaviour of earlier versions of XSLT.

    The class is a singleton marker class.

    See also bug 4752.
