Class Event  

java.lang.Object
  alice.tuplemedium.Event

All Implemented Interfaces:

java.io.Serializable

---

public class Event

extends java.lang.Object

implements java.io.Serializable

Represents internal events of the tuple centre virtual machine According to the tuple centre model, an event is characterised by the operation which caused the event, the tuple or the tuple template as information content of the operation, the direction of the event (from agent to the tuple centre, or viceversa), the identification of the agent responsible of the operation, the identification of the tuple centre where the event has happened.

Version:

Method Detail

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
