org.knime.core.util.MutableDouble

All Implemented Interfaces:

Serializable

public final class MutableDouble
extends Number

This class is essentially a double 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.
