Method Summary

Modifier and Type	Method	Description
int	basisSize()	Returns 2, indicating that the setBasis method expects an array of two atoms.
boolean	haveTarget(IAtom target)	Returns true if the iterator with its current basis would return an iterate for the given target.
int	nBody()	Returns the number of atoms given in each iterate, i.e., the size of the atom array returned with each call to next().
IAtomList	next()	Returns the next AtomSet iterate, or null if hasNext() is false.
void	reset()	Resets the iterator to loop through its iterates again.
void	setBasis(IMoleculeList basisMolecule)	Specifies the basis, which identifies the molecules subject to iteration.
void	setTarget(IAtom newTargetAtom)
int	size()	The number of iterates returned by this iterator in its current state.
void	unset()	Puts iterator in a state in which hasNext() returns false.

ANIntragroupExchange

public ANIntragroupExchange(int nBody,
                            int P)

Method Detail

unset

public void unset()

Description copied from interface: AtomsetIterator

Puts iterator in a state in which hasNext() returns false.

Specified by:

unset in interface AtomsetIterator

size

public int size()

Description copied from interface: AtomsetIterator

The number of iterates returned by this iterator in its current state.

Specified by:

size in interface AtomsetIterator

nBody

public final int nBody()

Description copied from interface: AtomsetIterator

Returns the number of atoms given in each iterate, i.e., the size of the atom array returned with each call to next().

Specified by:

nBody in interface AtomsetIterator

Returns:

next

public IAtomList next()

Description copied from interface: AtomLeafsetIterator

Returns the next AtomSet iterate, or null if hasNext() is false.

Specified by:

next in interface AtomLeafsetIterator

setTarget

public void setTarget(IAtom newTargetAtom)

Specified by:

setTarget in interface AtomsetIteratorTargetable

haveTarget

public boolean haveTarget(IAtom target)

Description copied from interface: AtomsetIteratorBasisDependent

Returns true if the iterator with its current basis would return an iterate for the given target.

Specified by:

haveTarget in interface AtomsetIteratorBasisDependent

setBasis

public void setBasis(IMoleculeList basisMolecule)

Specifies the basis, which identifies the molecules subject to iteration.

Specified by:

setBasis in interface AtomsetIteratorBasisDependent

Parameters:

basisMolecule - The basis atoms; a null basis will condition the iterator to give no iterates until a valid basis is specified via another call to this method.

reset

public void reset()

Description copied from interface: AtomsetIterator

Resets the iterator to loop through its iterates again.

Specified by:

reset in interface AtomsetIterator

basisSize

public int basisSize()

Returns 2, indicating that the setBasis method expects an array of two atoms.

Specified by:

basisSize in interface AtomsetIteratorBasisDependent

Returns:

the size of the basis for this iterator.
