SYNOPSIS

  use IOC::Service::SetterInjection;
  
  my $service = IOC::Service::SetterInjection->new('logger' => (
                    'FileLogger', 'new', [
                        # fetch a component from another container
                        { setLogFileHandle => '/filesystem/log_file_handle' },
                        # fetch a component from our own container
                        { setLogFileFormat => 'log_file_format' }
                    ]));

METHODS

new ($name, $component_class, $component_constructor, $setter_parameters)

Creates a service with a $name, and uses the $component_class and $component_constructor string arguments to initialize the service on demand.

If the $component_class and $component_constructor arguments are not defined, an IOC::InsufficientArguments exception will be thrown.

Upon request of the component managed by this service, an attempt will be made to load the $component_class. If that loading fails, an IOC::ClassLoadingError exception will be thrown with the details of the underlying error. If the $component_class loads successfully, then it will be inspected for an available $component_constructor method. If the $component_constructor method is not found, an IOC::ConstructorNotFound exception will be thrown. If the $component_constructor method is found, then it will be called.

Once a valid instance has been created, then the $setter_parameter array ref is looped through. Each parameter is then a hash ref, the key being the setter method name and the value being the name of a Service (available through "get" or "find"). It is then checked if the setter method is available, if not a IOC::MethodNotFound exception is thrown. It if is found, then it is called and passed the value of the resolved service name.
