method_changed_in

Force method-cache invalidation for $class and everything that inherits from it.

Synopsis

mro::method_changed_in($class);

Normally Perl notices method installations on its own and you do not need to call this. The one documented case that escapes automatic detection is installing a constant subroutine by aliasing a readonly scalar into the stash — the trick constant.pm uses internally. If you build something similar, call method_changed_in afterwards so cached dispatches pick up the new sub.

Croaks with No such class: '...'! if the stash for $class does not exist. A single argument is required; any other arity croaks with Usage: mro::method_changed_in(classname).
