Class AtomIteratorArrayListSimple

java.lang.Object
  etomica.atom.iterator.AtomIteratorArrayListSimple

All Implemented Interfaces:

AtomIterator, AtomLeafsetIterator, AtomsetIterator, Serializable

Direct Known Subclasses:

AtomIteratorArrayList, AtomIteratorBasis, AtomIteratorLeafAtoms

public class AtomIteratorArrayListSimple
extends Object
implements AtomIterator, Serializable

An atom iterator of the elements from an AtomArrayList (in proper sequence). Iterator will fail if element are added to or removed from list while iteration is proceeding.

Field Summary

protected AtomSetSinglet	atomSetSinglet
protected int	cursor Index of element to be returned by subsequent call to next.
protected IAtomList	list

Constructor Summary

AtomIteratorArrayListSimple()
Constructs new iterator with an empty list.

AtomIteratorArrayListSimple(IAtomList atomList)
Constructs new iterator set to iterate given list (upon reset).

Method Summary

int	nBody() Returns 1, indicating that this is an atom iterator.
IAtomList	next() Same as nextAtom().
IAtom	nextAtom() Returns the next iterate and advances the iterator.
void	reset() Puts iterator in state ready to begin iteration.
void	setList(IAtomList atomList) Sets the list for iteration.
int	size() Returns the number of iterates that would be given by this iterator if reset with the current list.
void	unset() Puts iterator in state in which hasNext is false.

Constructor Detail

AtomIteratorArrayListSimple

public AtomIteratorArrayListSimple()

Constructs new iterator with an empty list.

AtomIteratorArrayListSimple

public AtomIteratorArrayListSimple(IAtomList atomList)

Constructs new iterator set to iterate given list (upon reset).

Method Detail

setList

public void setList(IAtomList atomList)

Sets the list for iteration. Null value will result in a NullPointerException.

nBody

public int nBody()

Returns 1, indicating that this is an atom iterator.

Specified by:

nBody in interface AtomsetIterator

Returns:

unset

public void unset()

Puts iterator in state in which hasNext is false.

Specified by:

unset in interface AtomsetIterator

nextAtom

public IAtom nextAtom()

Returns the next iterate and advances the iterator.

Specified by:

nextAtom in interface AtomIterator

next

public IAtomList next()

Same as nextAtom().

Specified by:

next in interface AtomLeafsetIterator

size

public int size()

Returns the number of iterates that would be given by this iterator if reset with the current list.

Specified by:

size in interface AtomsetIterator

reset

public void reset()

Puts iterator in state ready to begin iteration.

Specified by:

reset in interface AtomsetIterator
