Detailed Description

Base interface for all actors in the system.

IActor defines the basic contract that all actors must implement. Actors receive messages through the Receive method and can respond by sending messages back through the provided context.

This is the synchronous version of actor interface - the Receive method should complete quickly and not block on I/O operations.

Member Function Documentation

AfterRegister()

virtual void NNet::NActors::IActor::AfterRegister ( TActorContext::TPtr )

inlinevirtual

Called once right after the actor is registered in the system.

Parameters

ctx	Context whose recipient is the actor itself; safe to Send/Schedule from here

Default implementation does nothing.

BeforeUnregister()

virtual void NNet::NActors::IActor::BeforeUnregister ( TActorContext::TPtr )

inlinevirtual

Called once on PoisonPill, right before the actor is destroyed.

Parameters

ctx	Context whose recipient is the actor itself

Not called when the whole TActorSystem is destroyed. Default does nothing.

Receive()

virtual void NNet::NActors::IActor::Receive ( TMessageId messageId, TBlob blob, TActorContext::TPtr ctx )

pure virtual

Process an incoming message.

Parameters

messageId	Type identifier of the message
blob	Serialized message data
ctx	Actor context for sending responses and accessing actor system

This method should process the message quickly and not perform blocking operations. For async operations, use ICoroActor instead.

Implemented in NNet::NActors::IBehaviorActor, NNet::NActors::ICoroActor, and NNet::NActors::TAsk< T >.
