      public final class PrologException
      extends JPLException

  PrologException instances wrap Prolog exceptions thrown (either by a Prolog engine or by user code) in the course of finding a solution to a Query. See JPLException for the handling of errors within the JPL Java-calls-Prolog interface.

  This class allows Java code which uses JPL's Java-calls-Prolog API to handle Prolog exceptions, which is in general necessary for hybrid Java+Prolog programming.

  Use the term() accessor to obtain a Term representation of the term that was thrown from within Prolog.
