Class MutableInteger

java.lang.Object
  java.lang.Number
      org.knime.core.util.MutableInteger

All Implemented Interfaces:

Serializable

public final class MutableInteger
extends Number

This class is essentially an integer whose value can be changed. The hash code and therefore also the equals change dynamically with the value stored. Be patient not to use this object as a key in a hashtable and such.
