EXPORTED FUNCTIONS

bare

bare $Type

bare Str

equivalent to this

is => 'bare', isa => Str

ro

ro $Type

ro Str

equivalent to this

is => 'ro', isa => Str,

rw

rw $Type

rw Str

equivalent to this

is => 'rw', isa => Str

required

required @rest

this

required rw Str

is equivalent to this

required => 1, is => 'rw', isa => Str,

this

rw Str, required

is equivalent to this

is => 'rw', isa => Str , required => 1

lazy

lazy @rest

like ( lazy => 1 , @rest )

lazy_build

lazy_build @rest

like ( lazy_build => 1, @rest )

weak_ref

weak_ref @rest

like ( weak_ref => 1, @rest )

coerce

@rest

like ( coerce => 1, @rest )

WARNING:

Conflicts with "MooseX::Types"

auto_deref

auto_deref @rest

like ( auto_deref => 1, @rest )

builder

builder $buildername:

required rw Str, builder '_build_foo'

is like

builder => '_build_foo'

predicate

predicate $predicatename

see "builder"

clearer

clearer $clearername

see "builder"

init_arg

init_arg $argname

default

default { $code }

Examples:

default { 1 }

$_ is localised as the same value as $_[0] for convenience ( usually $self )

trigger

trigger { $code }

Works exactly like default.

CONFLICTS

MooseX::Has::Sugar

MooseX::Has::Sugar::Minimal

This module is not intended to be used in conjunction with MooseX::Has::Sugar or MooseX::Has::Sugar::Minimal

We export many of the same symbols and its just not very sensible.

MooseX::Types

Moose::Util::TypeConstraints

due to exporting the "coerce" symbol, using us in the same scope as a call to

use MooseX::Types ....

or use Moose::Util::TypeConstraints

will result in a symbol collision.

We recommend using and creating proper type libraries instead, ( which will absolve you entirely of the need to use MooseX::Types and MooseX::Has::Sugar(::*)? in the same scope )

Perl 5.010 feature 'switch'

the keyword 'default' becomes part of Perl in both these cases:

use 5.010;
use feature qw( :switch );

As such, we can't have that keyword in that scenario.
