Interface ProcessorContext

public interface ProcessorContext

The context in which a processor runs. The processor should check this to discover what level of DEBUG output and histograms to produce, as well as where to write output, and what Random number generator to use. AbstractProcessor wraps this in some convenience routines to make access a little easier.
