Class EventType

java.lang.Object
  nl.tudelft.simulation.event.EventType

All Implemented Interfaces:

java.io.Serializable

public final class EventType

extends java.lang.Object

implements java.io.Serializable

The EventType is a masker used for the subscription to asynchronous events. Eventtypes are used by EventProducers to show which events they potentially fire. EventTypes should be defined as static final fields.

The EventType class is made final for a number of reasons. The most important is to assure that the equals and hashcode methods are not overloaded.

Constructor Detail

EventType

public EventType(java.lang.String name)

constructs a new EventType.

Parameters:

Method Detail

equals

public boolean equals(java.lang.Object arg0)

See Also:

Object.equals(java.lang.Object)

hashCode

public int hashCode()

Returns a hash code for the name of the this eventType. The hash code for an EventType object is computed as

 
   s[0]*31ˆ(n-1) + s[1]*31ˆ(n-2) + ... + s[n-1]
  
 

using int arithmetic, where s[i] is the i th character of the name of the eventType, n is the length of the name, and ^ indicates exponentiation. This algoritm assures JVM, host, time independency.

Returns:

a hash code value for this object.

toString

public java.lang.String toString()
