NAME

6       MooseX::Storage::Traits::OnlyWhenBuilt - A custom trait to bypass
7       serialization
8

SYNOPSIS

10           {   package Point;
11               use Moose;
12               use MooseX::Storage;
13
14               with Storage( traits => [qw|OnlyWhenBuilt|] );
15
16               has 'x' => (is => 'rw', lazy_build => 1 );
17               has 'y' => (is => 'rw', lazy_build => 1 );
18               has 'z' => (is => 'rw', builder => '_build_z' );
19
20               sub _build_x { 3 }
21               sub _build_y { expensive_computation() }
22               sub _build_z { 3 }
23
24           }
25
26           my $p = Point->new( 'x' => 4 );
27
28           # the result of ->pack will contain:
29           # { x => 4, z => 3 }
30           $p->pack;

DESCRIPTION

33       Sometimes you don't want a particular attribute to be part of the
34       serialization if it has not been built yet. If you invoke "Storage()"
35       as outlined in the "Synopsis", only attributes that have been built
36       (ie, where the predicate returns 'true') will be serialized.  This
37       avoids any potentially expensive computations.
38
39       See the SYNOPSIS for a nice example that can be easily cargo-culted.
