Bread::Board::Literal - service providing a literal value
version 0.37
my $c = container PrettyBoring => as {
# These are Bread::Board::Literal services
service connect_string => 'dbi:mysql:boring_db';
service service_url => 'http://api.example.com/v0/boring';
# And some other services depending on them...
service dbconn => (
class => 'DBI',
block => sub {
my $s = shift;
DBI->new($s->param('connect_string');
},
dependencies => wire_names(qw( connect_string )),
);
service service_request => (
class => 'HTTP::Request',
block => sub {
my $s = shift;
HTTP::Request->new(POST => $s->param('service_url'));
},
dependencies => wire_names(qw( service_url ));
};
};
# OR to use directly:
my $literal = Bread::Board::Literal->new(
name => 'the_answer_to_life_the_universe_and_everything',
value => 42,
);
$c->add_service($literal);
A literal service is one that stores a literal scalar or reference for use in your Bread::Board.
Beware of using references in your literals as they may cause your Bread::Board to leak memory. If this is a concern, you may want to weaken your references.
See "weaken" in Scalar::Util.
Required attribute with read/write accessor. This is the value that "get" will return.
Returns the "value", unaltered.
Dies: a literal service is (essentially) a constant, it does not make sense to inherit from it.
