MooseX::BuildArgs - Save the original constructor arguments for later use.


Create a class that uses this module:

    package MyClass;
    use Moose;
    use MooseX::BuildArgs;
    has foo => ( is=>'ro', isa=>'Str' );
    my $object = MyClass->new( foo => 32 );
    print $object->build_args->{foo};


Sometimes it is very useful to have access to the contructor arguments before builders, defaults, and coercion take affect. This module provides a build_args hashref attribute for all instances of the consuming class. The build_args attribute contains all arguments that were passed to the constructor.

A contrived case for this module would be for creating a clone of an object, so you could duplicate an object with the following code:

    my $obj1 = MyClass->new( foo => 32 );
    my $obj2 = MyClass->new( $obj1->build_args() );
    print $obj2->foo();
