getAlternateValueHolder

public BaseValueHolder getAlternateValueHolder(RandomValues randomValues)

Description copied from class: BaseValueHolder

Using the current values in this ValueHolder, return a new ValueHolder that has the same "value" in myValue and a new extraObject if extraObject is used. For example, if this.myValue contains a Long of value 34, the new ValueHolder will also have a myValue of 34, but it may be a String, an Integer, a BigInteger, etc.

Overrides:
