* An exception of this type is thrown if, in evaluating a Query,
|
||
|
|
* an exception is thrown in Prolog via the Prolog throw/1 predicate.

|
|
* <p>
|
||
|
|
* This method provides High-Level interface programmers to handle
|
||
|
|
* such exceptions, providing error management between Prolog and Java.
|

|
|
* <p>
|
||
|
|
* Use the exception_term() accessor to obtain the Term that was
|
||
|
|
* thrown via the throw/1 Prolog predicate.
