method wrap
Documentation for method wrap
assembled from the following types:
class Routine
From Routine
(Routine) method wrap
method wrap(Routine: )
Wraps (i.e. in-place modifies) the routine. That means a call to this routine first calls &wrapper
, which then can (but doesn't have to) call the original routine with the callsame
, callwith
, nextsame
and nextwith
dispatchers. The return value from the routine is also the return value from the wrapper.
wrap
returns an instance of a private class called Routine::WrapHandle
, which you can pass to unwrap to restore the original routine.
