# MooX::Role::CloneSet::BuildArgs(3pm)

create updated copies of truly immutable objects

## NAME

MooX::Role::CloneSet::BuildArgs - create updated copies of truly immutable objects

## SYNOPSIS

```
    package Someone;
    use Moo;
    with 'MooX::Role::CloneSet::BuildArgs';
    has name => (
        is => 'ro',
    );
    has race => (
        is => 'ro',
    );
    package main;
    my $first = Someone->new(name => 'Drizzt', race => 'drow');
    my $hybrid = $first->cset(race => 'dwarf');
    my $final = $weird->cset(name => 'Catti-brie', race => 'human');
```

## DESCRIPTION

`"MooX::Role::CloneSet::BuildArgs"` is a role very similar to `"MooX::Role::CloneSet"`; the only difference is that its `cset()` method does not try to obtain the current values of the object's attributes, but uses the ones the object was constructed with (using `"MooX::BuildArgs"`).

## METHODS

- •

  cset(field =\> value, ...)

  Shallowly clone the object, making the specified changes to its attributes.

  Note that this method obtains the names and values of the object's attributes by using the `build_args()` method from `"MooX::BuildArgs"`; thus, it really depends on the fact that none of the attributes has had its value changed since the object was constructed.
