NAME
MouseX::NativeTraits - Extend your attribute interfaces for Mouse
VERSION
This document describes MouseX::NativeTraits version 1.07.
SYNOPSIS
package MyClass;
use Mouse;
has mapping => (
traits => ['Hash'],
is => 'rw',
isa => 'HashRef[Str]',
default => sub { +{} },
handles => {
exists_in_mapping => 'exists',
ids_in_mapping => 'keys',
get_mapping => 'get',
set_mapping => 'set',
set_quantity => [ set => 'quantity' ],
},
);
DESCRIPTION
While Mouse attributes provide a way to name your accessors, readers, writers, clearers and predicates, MouseX::NativeTraits provides
commonly used attribute helper methods for more specific types of data.
As seen in the "SYNOPSIS", you specify the data structure via the "traits" parameter. These traits will be loaded automatically, so you
need not load MouseX::NativeTraits explicitly.
This extension is compatible with Moose native traits, although it is not a part of Mouse core.
PARAMETERS
handles
This is like "handles" in "has" in Mouse, but only HASH references are allowed. Keys are method names that you want installed locally, and
values are methods from the method providers (below). Currying with delegated methods works normally for "handles".
NATIVE TRAITS
Array
Common methods for array references.
has 'queue' => (
traits => ['Array'],
is => 'ro',
isa => 'ArrayRef[Str]',
default => sub { [] },
handles => {
add_item => 'push',
next_item => 'shift',
}
);
See MouseX::NativeTraits::ArrayRef.
Hash
Common methods for hash references.
has 'options' => (
traits => ['Hash'],
is => 'ro',
isa => 'HashRef[Str]',
default => sub { {} },
handles => {
set_option => 'set',
get_option => 'get',
has_option => 'exists',
}
);
See MouseX::NativeTraits::HashRef.
Code
Common methods for code references.
has 'callback' => (
traits => ['Code'],
is => 'ro',
isa => 'CodeRef',
default => sub { sub { 'called' } },
handles => {
call => 'execute',
}
);
See MouseX::NativeTraits::CodeRef.
Bool
Common methods for boolean values.
has 'is_lit' => (
traits => ['Bool'],
is => 'rw',
isa => 'Bool',
default => 0,
handles => {
illuminate => 'set',
darken => 'unset',
flip_switch => 'toggle',
is_dark => 'not',
}
);
See MouseX::NativeTraits::Bool.
String
Common methods for string operations.
has text => (
traits => ['String'],
is => 'rw',
isa => 'Str',
default => q{},
handles => {
add_text => 'append',
replace_text => 'replace', # or replace_globally
}
);
See MouseX::NativeTraits::Str.
Number
Common numerical operations.
has value => (
traits => ['Number'],
is => 'ro',
isa => 'Int',
default => 5,
handles => {
set => 'set',
add => 'add',
sub => 'sub',
mul => 'mul',
div => 'div',
mod => 'mod',
abs => 'abs',
}
);
See MouseX::NativeTraits::Num.
Counter
Methods for incrementing and decrementing a counter attribute.
has counter => (
traits => ['Counter'],
is => 'ro',
isa => 'Num',
default => 0,
handles => {
inc_counter => 'inc',
dec_counter => 'dec',
reset_counter => 'reset',
}
);
