Modifier and Type	Method	Description
double	getValue(int i)	Returns the value at index i zero indexed
boolean	hasNext()	Indicates to clients whether there is another value after the current value for the data source
double	next()	Advances to the next value and returns it.
void	reset()	This method should reset the IterativeDataSource so that it is positioned just prior to the 1st value to be returned via the use of the next() method Implementers should ensure that observers are notified of the reset and that the end of source indicator correctly reflects the reset

Method Detail

hasNext

public boolean hasNext()

Description copied from class: IterativeDataObservable

Indicates to clients whether there is another value after the current value for the data source

Specified by:

hasNext in class IterativeDataObservable

Returns:

next

public double next()

Description copied from class: IterativeDataObservable

Advances to the next value and returns it. Implementers must use setValue(double value) to properly set the current value. getValue() should then return this current value until advanced again Should throw a NoSuchElementException if there is no next value

Specified by:

next in class IterativeDataObservable

Returns:

reset

public void reset()

Description copied from class: IterativeDataObservable

This method should reset the IterativeDataSource so that it is positioned just prior to the 1st value to be returned via the use of the next() method Implementers should ensure that observers are notified of the reset and that the end of source indicator correctly reflects the reset

Specified by:

reset in class IterativeDataObservable

size

public int size()

The size of the array

Returns:

getValue

public double getValue(int i)

Returns the value at index i zero indexed

Parameters:

i -

Returns:

setValues

protected void setValues(double[] values,
                         int n)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
