evaluation_error/1¶
Description¶
evaluation_error(Exception)
Throws an evaluation error. This built-in predicate is declared as a private method and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of calls:
...,
context(Context),
throw(error(evaluation_error(Exception), Context)).
This allows the user to generate errors in the same format used by the runtime.
