=head1 NAME
Bread::Board::Types - types and coercions for Bread::Board
=head1 VERSION
version 0.37
=head1 DESCRIPTION
This package defines types and coercions for L<Bread::Board>.
=head1 TYPES
=head2 C<Bread::Board::Container::SubContainerList>
A hashref mapping strings to instances of L<Bread::Board::Container>
or L<Bread::Board::Container::Parameterized>.
Can be coerced from an arrayref of containers: the keys will be the
containers' names.
=head2 C<Bread::Board::Container::ServiceList>
A hashref mapping strings to instances of L<Bread::Board::Service>.
Can be coerced from an arrayref of services: the keys will be the
services' names.
=head2 C<Bread::Board::Service::Dependencies>
Hashref mapping strings to instances of L<Bread::Board::Dependency>.
The values of the hashref can be coerced in several different ways:
=over 4
=item a string
will be interpreted as the L<< C<service_path>|Bread::Board::Dependency/service_path >>
=item a hashref with a single key
the key will be interpreted as a L<<
C<service_path>|Bread::Board::Dependency/service_path >>, and the
value as a hashref for L<<
C<service_params>|Bread::Board::Dependency/service_params >>
=item an arrayref
each element will be interpreted as a dependency (possibly through all
the coercions listed here); see below for an example
=item a L<service|Bread::Board::Service> object
will be interpreted as a dependency on that service
=item a L<dependency|Bread::Board::Dependency> object
will be taken as-is
=back
Instead of a hashref of any of the above things, you can use an
arrayref: it will be coerced to hashref, using the (coerced)
dependencies' names as keys.
=head3 Examples
service foo => (
class => 'Foo',
dependencies => {
{ bar => { attribute => 12 } },
},
);
The service C<foo> depends on the parameterized service C<bar>, and
C<bar> will be instantiated passing the hashref C<< { attribute => 12
} >> to its L<< C<get>|Bread::Board::Service::WithParameters/get >>
method.
service foo => (
class => 'Foo',
dependencies => {
things => [ 'bar', 'baz' ],
},
);
The service C<foo> depends on the services C<bar> and C<baz>, and when
instantiating C<foo>, its constructor will receive something like C<<
things => [ $instance_of_bar, $instance_of_baz ] >>.
service foo => (
class => 'Foo',
dependencies => {
things => [
{ bar => { attribute => 12 } },
{ bar => { attribute => 27 } },
],
},
);
You can mix&match the coercions! This C<foo> will get two different
instances of C<bar> in its C<things> attribute, each C<bar>
instantiated with a different value.
=head2 C<Bread::Board::Service::Parameters>
Hashref mapping strings to L<MooseX::Params::Validate> specifications.
Can be coerced from an arrayref of strings:
[qw(a b c)]
becomes:
{
a => { optional => 0 },
b => { optional => 0 },
c => { optional => 0 },
}
