Scope::Guard - lexically scoped resource management my $sg = Scope::Guard->new(sub { ... }); # or my $sg = Scope::Guard->new(\&handler); $sg->dismiss(); # disable the handler This module provides a convenient way to perform cleanup or other forms of resource management at the end of a scope. It is particularly useful when dealing with exceptions: the Scope::Guard constructor takes a reference to a subroutine that is guaranteed to be called even if the thread of execution is aborted prematurely. This effectively allows lexically-scoped "promises" to be made that are automatically honoured by perl's garbage collector.

new
usage my $sg = Scope::Guard->new(sub { ... }); # or my $sg = Scope::Guard->new(\&handler); description Create a new Scope::Guard object which calls the supplied handler when its "DESTROY" method is called, typically when it goes out of scope.

dismiss
usage $sg->dismiss(); # or $sg->dismiss(1); description Detach the handler from the Scope::Guard object. This revokes the "promise" to call the handler when the object is destroyed. The handler can be re-enabled by calling: $sg->dismiss(0); 0.03 chocolateboy: <chocolate.boy@email.com> Copyright (c) 2005-2007, chocolateboy. This module is free software.
