check_predicate_option
(:PI, +Arg, +Option)
is
det
Verify predicate options at runtime. Similar to
current_predicate_option/3
, but intended to support runtime checking.
Errors
-
existence_error(option, OptionName)
if the option is not supported by
PI
.
-
type_error(Type, Value)
if the option is supported but the value does not match the option type. See
must_be/2
.
