# MooX::BuildArgs(3pm)

Save instantiation arguments for later use.

## NAME

MooX::BuildArgs - Save instantiation arguments for later use.

## SYNOPSIS

```
    package Foo;
    use Moo;
    with 'MooX::BuildArgs';
    has bar => (is => 'ro');

    my $foo = Foo->new( bar => 32 );
    print $foo->build_args->{bar}; # 32
```

## DESCRIPTION

It is often useful to be able to access the arguments that were used to create an object in their unadulterated form, before any coercions or init\_args have changed them.  This Moo role provides the arguments via the "build\_args" attribute.

Note that no attempt is made to weaken the args.  So, if you use this module and you have attributes with `"weak_ref"` set the references will not be weakened within "build\_args".

## ATTRIBUTES

### build\_args

```
    my $args_hashref = $object->build_args();
```

Returns a hashref containing the captured arguments.
