method

register_hook

v7.1.3.2 - Show latest stable - Class: ActiveSupport::ExecutionWrapper

register_hook(hook, outer: false)

public

hook.complete will be passed the value returned from hook.run, and will only be invoked if run has previously been called. (Mostly, this means it won’t be invoked if an exception occurs in a preceding to_run block; all ordinary to_complete blocks are invoked in that situation.)
