MooseX::PrivateSetters - Names your accessors foo() and _set_foo()


    use Moose;
    use MooseX::PrivateSetters;

    # make some attributes

    has 'foo' => ( is => 'rw' );

    package main;

    sub bar {
        $self = shift;
        $self->_set_foo(1) unless $self->foo


This module does not provide any methods. Simply loading it changes the default naming policy for the loading class so that accessors are separated into get and set methods. The get methods have the same name as the accessor, while set methods are prefixed with _set_.

If you declare an attribute with a leading underscore, then the set method will start with "_set" (i.e. has '_foo' will get a setter called _set_foo. Note that if you have attributes foo and _foo, they will both get a setter called _set_foo, so don't do that.

If you explicitly set a reader or writer name when creating an attribute, then that attribute's naming scheme is left unchanged.

Load order of this module is important. It must be used after Moose.


There are a number of similar modules on the CPAN.


The original. A single mutator method is generated with the same name as the attribute itself.


Changes the parsing of the is clause, making new options available. For example,

    has baz => ( is => 'rpwp', # private reader, private writer

gets you _get_baz() and _set_baz.


Names accessors in the style recommended by Perl Best Practices: get_size and set_size.


Has separate methods for getting and setting. The getter has the same name as the attribute, and the setter is prefixed with set_.
