Implementation

def self.wrap(environment)
	evaluator = environment.evaluator
	
	if evaluator.key?(:service_class)
		if service_class = evaluator.service_class
			return service_class.new(environment, evaluator)
		end
	end
end

`def initialize(environment, evaluator = environment.evaluator)`

Initialize the service from the given environment.

Signature

parameter　environment　Environment

Implementation

def initialize(environment, evaluator = environment.evaluator)
	@environment = environment
	@evaluator = evaluator
end

`attr :environment`

Signature

attribute　Environment: The environment which is used to configure the service.

`def to_h`

Convert the service evaluator to a hash.

Signature

returns　Hash: A hash representation of the evaluator.

Implementation

def to_h

Implementation

def name
	@evaluator.name
end

`def start`

Implementation

def start
	Console.debug(self){"Starting service #{self.name}..."}
end

`def setup(container)`

Setup the service into the specified container.

Signature

parameter　container　Async::Container::Generic

Implementation

def setup(container)
	Console.debug(self){"Setting up service #{self.name}..."}
end

`def stop(graceful = true)`

Stop the service. Called after the container is stopped.

Implementation

def stop(graceful = true)
	Console.debug(self){"Stopping service #{self.name}..."}
end
