All Implemented Interfaces:

DataGenerator

public class SeriesGenerator
extends NumberGenerator

Generates a series of numbers, starting with min and incrementing by increment if it is set, or 1.0 if no increment is set. If max is set, if the next number to be returned is >= max, then the counter will loop back around to min. If increment is negative, the counter will move from max to min.

SeriesGenerator

public SeriesGenerator()

Method Detail

init

protected boolean init()

Description copied from class: NumberGenerator

Returns true if init has already been called. False if this was the first time to call it. Useful for any sub-classes that call this so they can tell if they need to do any of their initialization stuff.

Overrides:

init in class NumberGenerator

generateRealData

protected java.lang.Object generateRealData(DataGeneratorContext context)

Description copied from class: NumberGenerator

Return a random number in the proper range. If either min or max is not specified, the min and max value for dataClass are used.

Overrides:

generateRealData in class NumberGenerator

Returns:

The returned object will be of the same type as dataClass

testData

protected boolean testData(java.lang.Object testItem,
                           DataGeneratorContext context)

Checks that the item is within the specified range and that it could be hit with the set increment amount. This is actually pretty hard to do accurately for decimals. Thus, we just make sure the testItem is very close.

Overrides:

testData in class NumberGenerator

getIncrement

public double getIncrement()

Returns:

Returns the increment.

setIncrement

public void setIncrement(double increment)

Parameters:

increment - The increment to set.
