meta_predicate/1

Description

meta_predicate(MetaPredicate)

Declares meta-predicates, i.e., predicates that have arguments that will be called as goals. An argument may also be a closure instead of a goal if the meta-predicate uses the call/N Logtalk built-in methods to construct the actual goal from the closure and the additional arguments.
