NAME

MooseX::Role::UnsafeConstructable - construct an object without type-checks

VERSION

Version 0.03

SYNOPSIS

This module provides the method unsafe_new which allows the caller to construct an instance while bypassing all access controls and type constraints. This is useful when the caller knows and trusts the source of the initialization data and doesn't want to choose between performance in a corner case and data integrity of the overall system.

Example usage:

        package Foo;
        use Moose;
        with 'MooseX::Role::UnsafeConstructable';

        has field => (is => 'ro', isa => 'HashRef[ArrayRef[Str]]');

        __PACKAGE__->meta->make_immutable;

        package main;

        my $foo = Foo->unsafe_new(field => {this => [qw{that and another}]});
                # => is a Foo, but instantiated faster

METHODS

declare_unsafe_class

Declare the shadow class to be used for unsafe instantiation. Any class using MooseX::Role::UnsafeConstructable role will call declare_unsafe_class automatically when made immutable. Otherwise, declare_unsafe_class must be called after the original class is fully declared to ensure all attributes are properly shadowed.

For each attribute, the shadow class will preserve: name, default, builder, and init_arg. All other options will be dropped. This should provide behavior that mostly matches normal instantiation, with the one caveat that any field declared uninitializable (with init_arg => undef) can now be set. This is considered a feature, not a bug.

unsafe_class

Return the name of the shadow class used for unsafe instantiation.

unsafe_new

Instantiate the class, bypassing access and type constraints.
