Constructor Summary

DoubleAbstractFilteringIteratorDecorator(DoubleIterator iter)           Initialize this iterator decorator

DoubleAbstractFilteringIteratorDecorator(DoubleIterator iter, double ignored)           Partially intialize this iterator decorator, with a call to initialize needed after this call.

 

Method Summary

boolean	atEnd()           Is this iterator at its end?
Object	clone()           Return a copy of this iterator in the same state as this object.
double	getDouble()           Return the current approved element.
void	initialize()           Complete initialization of this object.
private  void	setCursor()           Set the cursor to the next element that is approved, if any.

DoubleAbstractFilteringIteratorDecorator

public DoubleAbstractFilteringIteratorDecorator(DoubleIterator iter)

Initialize this iterator decorator

DoubleAbstractFilteringIteratorDecorator

public DoubleAbstractFilteringIteratorDecorator(DoubleIterator iter,
                                                double ignored)

Partially intialize this iterator decorator, with a call to initialize needed after this call.

initialize

public void initialize()

Complete initialization of this object.

setCursor

private void setCursor()

Set the cursor to the next element that is approved, if any.

approve

public abstract boolean approve(double elem)

Return true if the element is to be returned by the getDouble() method.

atEnd

public boolean atEnd()

Description copied from interface: IndefiniteIterator

Is this iterator at its end? That is, if we called get(), would it throw an exception?

getDouble

public double getDouble()
                 throws NoSuchElementException

Return the current approved element.

Throws:

NoSuchElementException

advance

public void advance()

Description copied from interface: IndefiniteIterator

Advance the state of this iteration to the next position. Note that this never throws an exception.

clone

public Object clone()

Description copied from interface: DoubleIterator

Return a copy of this iterator in the same state as this object.

Specified by:

clone in interface DoubleIterator

Overrides:

clone in class DoubleAbstractIterator

toString

public String toString()

Overrides:

toString in class Object
