Amp\CallableMaker
is a helper trait that allows creating closures from private / protected static and instance methods in an easy way. Creating such callables might be necessary to register private / protected methods as callbacks in an efficient manner without making those methods public.
This trait should only be used in projects with a PHP 7.0 minimum requirement. If PHP 7.1 or later are the minimum requirement, Closure::fromCallable
should be used directly.
callableFromInstanceMethod()
Creates a Closure
form an instance method with the given name and returns it. The closure can be passed around without worrying about the method's visibility.
callableFromStaticMethod()
Same as callableFromInstanceMethod()
, but for static methods.
