Class NumberGenerator

java.lang.Object
  org.progeeks.tool.gen.BaseDataGenerator
      org.progeeks.tool.gen.NumberGenerator

All Implemented Interfaces:

DataGenerator

Direct Known Subclasses:

SeriesGenerator

public class NumberGenerator
extends BaseDataGenerator

Generates a number within a specified range. Uses dataClass to determine what type of number to return. If dataClass is not set, defaults to Double.

NOTE: Like most Java functionality relating to ranges of numbers, Min value is inclusive and max value is exclusive.

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

init

protected boolean init()

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.

testData

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

Checks if the given item meets the criteria set for this generator. Assumes that the object is of the proper type.

Specified by:

testData in class BaseDataGenerator

generateRealData

protected java.lang.Object generateRealData(DataGeneratorContext context)

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.

Specified by:

generateRealData in class BaseDataGenerator

Returns:

The returned object will be of the same type as dataClass

createNumber

protected java.lang.Number createNumber(double val)

Creates a number object of the same type as #numberClass

Parameters:

val -

verifyMinMax

protected void verifyMinMax()

Make sure it's possible to generate a number in the proper range

getMax

public double getMax()

Returns:

Returns the max.

getMin

public double getMin()

Returns:

Returns the min.

setMax

public void setMax(double max)

Parameters:

max - The max to set.

setMin

public void setMin(double min)

Parameters:

min - The min to set.

setDataClass

public void setDataClass(java.lang.String dataClass)

Description copied from class: BaseDataGenerator

The full java class name or a MetaClass name of the objects to create

Specified by:

setDataClass in interface DataGenerator

Overrides:

setDataClass in class BaseDataGenerator

Parameters:

dataClass - The dataClass to set.
