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.
BUGS
Please report any bugs to
SEE ALSO
No::Die.
The $_try function from Object::Util is a different way to achieve a
similar effect.
