NAME

MooseX::Attribute::LazyInflator - Lazy inflate attributes on access for better performance

VERSION

version 2.2.2

SYNOPSIS

            

              
              
package Test;
use Moose;
use MooseX::Attribute::LazyInflator;
# Load default deflators and inflators
use MooseX::Attribute::Deflator::Moose;
has hash => ( is => 'rw', 
             isa => 'HashRef',
             traits => ['LazyInflator'] );
package main;
my $obj = Test->new( hash => '{"foo":"bar"}' );
# Attribute 'hash' is being inflated to a HashRef on access
$obj->hash;
            
          

DESCRIPTION

Using coerce will inflate an object on construction even if it is not needed. This has the advantage, that type constraints are being called but on the other hand it is rather slow.

This module will defer object inflation and constraint validation until it is first accessed. Furthermore the advantages of inflate apply as well.
