MooX::Role::CloneSet::BuildArgs

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.
