type_error/2¶
Description¶
type_error(Type, Culprit)
Throws a type 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
where Head
is the head of the predicate clause making the call:
...,
context(Context),
throw(error(type_error(Type,Culprit), logtalk(Head,Context))).
This allows the user to generate errors in the same format used by the runtime.
