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

see ``builder''

default

default { $code }

Examples:

     default { 1 }
     default { { } }
     default { [ ] }
     default { $_->otherfield }
 
 

$_ 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.
