Constructor Summary

BooleanAbstractFilteringIteratorDecorator(BooleanIterator iter)           Initialize this iterator decorator

BooleanAbstractFilteringIteratorDecorator(BooleanIterator iter, boolean ignored)           Partially intialize this iterator decorator, with a call to initialize needed after this call.

 

Method Summary

abstract  boolean	approve(boolean elem)           Return true if the element is to be returned by the getBoolean() method.
boolean	atEnd()           Is this iterator at its end?
Object	clone()           Return a copy of this iterator in the same state as this object.
boolean	getBoolean()           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.

BooleanAbstractFilteringIteratorDecorator

public BooleanAbstractFilteringIteratorDecorator(BooleanIterator iter)

Initialize this iterator decorator

BooleanAbstractFilteringIteratorDecorator

public BooleanAbstractFilteringIteratorDecorator(BooleanIterator iter,
                                                 boolean 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(boolean elem)

Return true if the element is to be returned by the getBoolean() 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?

getBoolean

public boolean getBoolean()
                   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: BooleanIterator

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

Specified by:

clone in interface BooleanIterator

Overrides:

clone in class BooleanAbstractIterator

toString

public String toString()

Overrides:

toString in class Object
