NAME

Data::Object::Role::Tryable

ABSTRACT

Tryable Role for Perl 5

SYNOPSIS

package Example;

use Moo;

with 'Data::Object::Role::Tryable';

package main;

use routines;

my $example = Example->new;

DESCRIPTION

This package provides a wrapper around the Data::Object::Try class which provides an object-oriented interface for performing complex try/catch operations.

METHODS

This package implements the following methods:

try

try(CodeRef | Str $method) : InstanceOf['Data::Object::Try']

The try method takes a method name or coderef and returns a Data::Object::Try object with the current object passed as the invocant which means that try and finally callbacks will receive that as the first argument.

try example #1

# given: synopsis

my $tryer = $example->try(fun(@args) {
  [@args]
});

# $tryer->result(...)

try example #2

# given: synopsis

my $tryer = $example->try(fun(@args) {
  die 'tried';
});

$tryer->default(fun($error) {
  return ['tried'] if $error =~ 'tried';
  return [$error];
});

# $tryer->result(...)
