CommandableCloudFunctionService

Extends: CloudFunctionService

Description

The CommandableCloudFunctionService class allows you to create abstract services that receive commands via the Google Function protocols to operations automatically generated for commnads defined in ICommandable components.

Important points

• Each command is exposed as an invoke method that receives a command’s name and parameters.

• Commandable services require only 3 lines of code to implement a robust external Google Function-based remote interface.

• This service is intended to work inside an Google Function 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

Creates a new instance of the service.

public CommandableCloudFunctionService(string name)

• name: string - service’s name.

Creates a new instance of the service.

public CommandableCloudFunctionService()

Instance methods

Examples

class MyCommandableCloudFunctionService : CommandableCloudFunctionService
{
    private IMyController _controller;
    // ...
    public MyCommandableCloudFunctionService() : base()
    {
        this._dependencyResolver.Put(
            "controller",
            new Descriptor("mygroup", "controller", "*", "*", "1.0")
        );
    }
}

/// ...

var service = new MyCommandableCloudFunctionService();
service.SetReferences(References.FromTuples(
   new Descriptor("mygroup", "controller", "default", "default", "1.0"), controller
));
await service.OpenAsync("123");

Console.WriteLine("The Google Function service is running");
