NAME
Die::Hard - objects as resistant to dying as John Maclane
SYNOPSIS
my $fragile = Fragile::Object->new;
my $diehard = Die::Hard->new($fragile);
$diehard->isa('Fragile::Object'); # true
$diehard->method_that_will_die; # lives!
$fragile->method_that_will_die; # dies!
DESCRIPTION
Die::Hard allows you to create fairly transparent wrapper object that delegates all method calls through to the wrapped object, but does so within an eval { ... }
block. If the wrapped method call dies, then it sets a last_error
attribute.
Constructor
new(%attributes)
-
Standard Moose-style constructor.
new($object)
-
Shortcut for setting the
proxy_for
attribute.
Attributes
proxy_for
-
The object being wrapped. Read-only; required.
last_error
-
If the last proxied method call died, then this attribute will contain the error. Otherwise will be undef.
Methods
isa
-
Tells lies; claims to be the object it's proxying.
DOES
-
Tells the truth; claims to do the object it's proxying.
can
-
Tells the truth; claims it can do anything the object it's proxying can do.

function from Object::Util is a different way to achieve a similar effect.
