Class EventType

java.lang.Object

nl.tudelft.simulation.event.EventType

All Implemented Interfaces:

Serializable

public final class EventType
extends Object
implements 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.

EventType

public EventType(String name)

constructs a new EventType.

Parameters:

name - the name of this eventType. Two values are not appreciated : null and "".

Method Detail

equals

public boolean equals(Object arg0)

Overrides:

equals in class Object

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.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

toString

public String toString()

Overrides:

toString in class Object

Object.toString()
