Question

perl object “plan” has subroutine “plan_exec_time“;

my $p = Plan->new;

i can call it by this way : $p->plan_exec_time

but $p->"plan_exec_time" dos not works.

now i want access the subroutine by variable refer:

my $t = "plan_exec_";

$p->"${t}time"

this is also not works

how to access the object’s subroutine but donot through create an temp variable ?

because this works :

my $x = "${t}time";
$p->$x;

Answer 1

my $t = "plan_exec";
$p->can($t."_time")->($p)

The can method returns ref to the method.
