Class DoubleValueObject

java.lang.Object

com.ergotech.vib.valueobjects.ValueObject

com.ergotech.vib.valueobjects.DoubleValueObject

All Implemented Interfaces:

ValueObjectInterface, java.lang.Cloneable

public class DoubleValueObject
extends ValueObject

This is the instance of ValueObject that is created when you use the setBoolValue(), setIntValue(), setFloatValue() and setStringValue(). Notice that this method does not store Objects. This is because we can not copy an Object and all ValueObjects must be able to copy themselves.
