NAME

hide-methods - hide methods of classes during runtime

SYNOPSIS

use hide-methods;

class A {
    method foo() { say "foo" }
}

A.foo;  # foo

hide-methods(A,"foo");
A.foo;  # X::Method::NotFound

class B {
    method bar() { say "bar" }
}

B.bar;  # bar

my $vault = B.&hide-methods("bar");
B.bar;  # X::Method::NotFound

$vault.unhide-methods("bar");
B.bar;  # bar

DESCRIPTION

hide-methods is a module that exports a single subroutine called hide-methods. Calling this subroutine with a class and one or more method names, will hide the indicated methods from execution, resulting in either having a X::Method::NotFound exception thrown, or a method with the same name called from a parent class (if that doesn't happen to be hidden as well, of course).

Handles standard method call dispatch and the .can method on classes. Does not affect dispatch through .?, .+ or .*, or listing with the .^methods method.

SUBROUTINES

hide-methods

hide-methods(A,<foo bar baz>);   # hide "foo","bar","baz" methods in A
A.&hide-methods(<foo bar baz>);  # same, using method syntax

my $vault = hide-methods(B,"zippo");  # allow unhiding

$vault.unhide-methods("zippo");  # make B.zippo available again

The hide-methods subroutine takes a class as the first parameter, and one or more names of methods to hide. It returns a Vault object that supports a unhide-methods method, that takes the names of the methods that should become available again.
