All Implemented Interfaces:

AtomLeafsetIterator, AtomsetIterator, AtomsetIteratorBasisDependent, AtomsetIteratorTargetable

public class Atomset4IteratorIndexList
extends java.lang.Object
implements AtomsetIteratorBasisDependent

Atomset Iterator that iterates over set-of-four atoms

Constructor Summary

Constructors

Constructor	Description
Atomset4IteratorIndexList(int[][] index)	Constructs iterator without defining set of atoms.

Method Summary

Modifier and Type	Method	Description
int	basisSize()	Indicates the size of the basis needed to set the iterator.
protected boolean	hasNext()	Returns true if three non-null atoms have set and a call to reset() has been performed, without any subsequent calls to next() or nextPair().
boolean	haveTarget(IAtom a)	Returns true if the iterator with its current basis would return an iterate for the given target.
int	nBody()	Returns 4, indicating that this is a set of four iterator.
IAtomList	next()	Returns the next AtomSet iterate, or null if hasNext() is false.
void	reset()	Resets iterator to a state where hasNext is true, if atoms in pair are not null.
void	setBasis(IMoleculeList parent)	Identifies the atoms that form the basis for iteration, such that the childList atoms of those given will form the iterates.
void	setTarget(IAtom a)
int	size()	The number of iterates returned by this iterator in its current state.
void	unset()	Sets iterator to a state where hasNext() returns false.

Constructor Detail

Atomset4IteratorIndexList

public Atomset4IteratorIndexList(int[][] index)

Constructs iterator without defining set of atoms.

Method Detail

basisSize

public int basisSize()

Description copied from interface: AtomsetIteratorBasisDependent

Indicates the size of the basis needed to set the iterator. The length of the array given to setBasis should be this value.

Specified by:

basisSize in interface AtomsetIteratorBasisDependent

Returns:

the size of the basis for this iterator.

haveTarget

public boolean haveTarget(IAtom a)

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

setTarget

public void setTarget(IAtom a)

Specified by:

setTarget in interface AtomsetIteratorTargetable

setBasis

public void setBasis(IMoleculeList parent)

Description copied from interface: AtomsetIteratorBasisDependent

Identifies the atoms that form the basis for iteration, such that the childList atoms of those given will form the iterates.

Specified by:

setBasis in interface AtomsetIteratorBasisDependent

Parameters:

parent - 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.

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

hasNext

protected boolean hasNext()

Returns true if three non-null atoms have set and a call to reset() has been performed, without any subsequent calls to next() or nextPair().

unset

public void unset()

Sets iterator to a state where hasNext() returns false.

Specified by:

unset in interface AtomsetIterator

reset

public void reset()

Resets iterator to a state where hasNext is true, if atoms in pair are not null.

Specified by:

reset in interface AtomsetIterator

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

nBody

public final int nBody()

Returns 4, indicating that this is a set of four iterator.

Specified by:

nBody in interface AtomsetIterator

Returns:
