Class StrongReference

java.lang.Object
  nl.tudelft.simulation.event.ref.StrongReference

All Implemented Interfaces:

Reference, java.io.Serializable

public class StrongReference

extends java.lang.Object

implements Reference, java.io.Serializable

A StrongReference class represents a normal pointer relation to a reference. This class is created to complete the java.lang.ref package. This class ensures that references can be used without casting to either an object or a reference. Strong references are not created to be cleaned by the garbage collector. Since they represent normal pointer relations, they are the only ones which might be serialized. This class therefore implements java.io.Serializable
