    public interface RDFStream
    extends java.io.Closeable
    A simple interface for representing a stream for RDF input. An RDF stream is typically backed by an input stream and parsed with an RDFParser but a specific stream implementation might use different means to generate statements.

        Resource getContext()
        Returns the default context associated with this stream or null if there is no default context. Note that, the statements that will be sent to the handler may not be using this context and the user of this stream should make sure the context information is used correctly.

        boolean hasContext()
        Returns true either if this stream has a non-null context or the statements generated by this stream has contexts.
