EvaluateBase

public EvaluateBase()
             throws java.lang.Exception

Create a new instance of Evaluate.

Throws:

java.lang.Exception - any error.

Method Detail

valueFromSet

public static <T> T valueFromSet(java.lang.Object value)

Get the single value in what might be a wrapped data object.

Parameters:

value - data value.

Returns:

the value or stored value of a dataset, for example.

randomValue

public static <T> java.lang.Object randomValue(java.lang.String valueType,
                                               java.util.Random rnd,
