org.jpl7.JPLException

All Implemented Interfaces:

java.io.Serializable

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.
