CommandableLambdaService

Abstract service that receives commands via the AWS Lambda protocol to operations automatically generated for commands defined in ICommandable components. Each command is exposed as an invoke method that receives a command’s name and parameters.

Implements: LambdaService

Description

The CommandableLambdaService allows you to create abstract services that receive commands via the AWS Lambda protocol to operations automatically generated for commands defined in ICommandable components. Each command is exposed as an invoke method that receives a command’s name and parameters.

Important points

  • This service is intended to work inside a LambdaFunction container that exploses registered actions externally.

Configuration parameters

  • dependencies:
    • controller: override for Controller dependency

References

  • *:logger:*:*:1.0: (optional) ILogger components to pass log messages.
  • *:counters:*:*:1.0: (optional) ICounters components to pass collected measurements.

Constructors

InheritCommandableLambdaService

Creates a new instance of the service.

InheritCommandableLambdaService(overrides ILambdaServiceOverrides, name string) *CommandableLambdaService

  • overrides: ILambdaServiceOverrides - Lambda service overrides.
  • name: string - service name.

Methods

Register

Registers all actions in AWS Lambda function.

(c *CommandableLambdaService) Register()

Examples

type MyCommandableLambdaService struct  {
	*CommandableLambdaService
}

func NewMyCommandableLambdaService() *MyCommandableLambdaService {
	c:= &MyCommandableLambdaService{
		CommandableLambdaService: NewCommandableLambdaService("v1.service")
	}
	c.DependencyResolver.Put(context.Background(),
		"controller",
		cref.NewDescriptor("mygroup","controller","*","*","1.0")
	)
	return c
}

service := NewMyCommandableLambdaService();
service.SetReferences(context.Background(), NewReferencesFromTuples(
   NewDescriptor("mygroup","controller","default","default","1.0"), controller
))

service.Open(context.Background(),"123")
fmt.Println("The AWS Lambda 'v1.service' service is running")
