state at which the thread is eligible to run. In fact, this three-state combination is one, and its common denominator is that the thread is still alive, but there is no condition to run at the moment. In other words, it is operational, but if an event occurs, he may return to the operational state.5. Death state: When the thread's run () method finishes, it is considered dead. This thread object may be alive, but it is not a separate thread. Once a thread dies, it cannot be resurrected. If you

Akka send a message to the actor in the following way! Tell means "Fire-and-forget", that is, asynchronously sending a message without waiting for the result to be returned ? Ask asynchronously sends a message and returns a future that represents a possible reply. Messages are ordered on a per-sender basis. MailBox The Akka mailbox contains messages destined for the actor. Usually each

What is Akka. It provides the Actor programming model on the JVM-both concurrency and distribution. It was written by Scala, instead of the Actor of Scala itself. The Actor's vision is a heavyweight resource, capable of higher concurrency with a small amount of memory, something like a fiber, a process. One data comparison is the same 1GB memory, can create 2.7M actors, and threads can only create 4,096, fo

class-based actorsA class-based actor is a subtype of event_based_actor and must implement the pure virtual member function Make_behavior re Turning the initial behavior.The exact words tell us two points: 1. "Event_based_actor" must be inherited.2. The function of overloading Make_behavior is actually the constructor of this class, which defines the initial behavior.About the 1th, that this class can use a lot of basic send, read a little bit of sour

library that would cause coredump and output a bunch of things that could be CAF's own stuff without going deep and so on,There is delay_send I started a bit silly, want to use Delay_send to reply sent over the message, so the actor, but to find out "send" and "reply" is two things, you can not send to reply, can only use return to replyd). Synchronous send, synchronous wait. Applies the blocking actor API

Scala's most attractive point is actor's concurrent programming. However, looking at Scala official documents, Baidu documents and IBM documents, all of them are passed through strings. If they are used as actor programming, there is certainly no problem. However, in the official opening process, the light transfer string is obviously weak. So how to transfer objects? First, let's look at the model for passing messages through strings: Message receivi

Introduction Akka Before you need to say a little bit scala,scala claims to be the next generation JVM language, The integration of the object-oriented Java, as well as functional programming in one, unusually powerful, but also complex, this article is not controversial, let's briefly introduce. The Akka framework is based on Scala and a small amount of Java code, and Scala replaces its own underlying actor library with Akka from its 2.11.0 version,

Every time the stars of the week repeat the phrase "I am actually an actor", I always think of myself. Everyone wants to assume a good or bad role in this world, but no one wants to be a running man. As a result, Zhou Xingxing gave me a casual smile on TV, and told everyone with great importance that when I was an actor, I thought he would tell everyone the best of his life. At the same time, I think he

Seeing Usermanual (using the essay one) saw almost half of the time, the combination of Keep_behavior and unbeacome caught my eye. (What is this for?) ）Because its sample code is too simple to write! I really did not see too understand, I will change his own to put up.First of all, the basic concept is that an actor can have multiple behaviors (behavior) so become can make an actor into a behavior.If Keep_b
