Bread::Board::Service::WithParameters - Services with parameters
version 0.37
This is a sub-role of Bread::Board::Service, for parameterized services. These are services that will instantiate different values depending on parameters that are passed to the "get" method. You can pass those parameters via the "service_params" attribute of "Bread::Board::Dependency", or via the "inflate" method of "Bread::Board::Service::Deferred::Thunk".
Read-only hashref, will be passed as-is to "MooseX::Params::Validate"'s "validated_hash", so you can use things like "optional" and "default" in addition to type constraints:
service something => ( class => 'Thing', parameters => { type => { isa => 'Str', default => 'text' }, }, );
This attribute uses coercions on "Bread::Board::Service::Parameters" so that you can also say:
service something => ( class => 'Thing', parameters => ['type'], );
and it will be equivalent to:
service something => ( class => 'Thing', parameters => { type => { optional => 0 }, }, );
Predicate for the "parameters" attribute.
Returns true if any of the "parameters" have a "default" value.
Returns true if any of the "parameters" does not have "optional" set to true.
my %parameters = $service->check_parameters(name1=>$value1,name2=>$value2); my %parameters = $service->check_parameters({name1=>$value1,name2=>$value2});
If any "parameters" are defined, this function validates its arguments against the parameters' definitions (using MooseX::Params::Validate). It will die if the validation fails, or return the validated parameters (including default value) if it succeeds.
Before the "get" method, arguments to "get" are passed through "check_parameters" and added to the "params" hashref. After the "get" method, those keys/values will be removed. In practice, this makes all parameters available to the actual "get" method body.
