Method Summary

void	crossAtomPairTraversed(AtomPair pair) Implement this method to receive notification that a cross AtomPair has been traversed.
void	layerFinished(int layerIndex) Implement this method to receive notification that the layer containing Atoms a distance of layerIndex from the root Atom has been exited.
void	layerStarted(int layerIndex) Implement this method to receive notification that the next layer, a distance of layerIndex atoms away fromt the root Atom, has been entered.

Method Detail

layerStarted

public void layerStarted(int layerIndex)

Implement this method to receive notification that the next layer, a distance of layerIndex atoms away fromt the root Atom, has been entered.

Parameters:

layerIndex - the atomic distance of the Atoms in this layer from the root Atom

layerFinished

public void layerFinished(int layerIndex)

Implement this method to receive notification that the layer containing Atoms a distance of layerIndex from the root Atom has been exited.

Parameters:

layerIndex - the atomic distance of the Atoms in this layer from the root Atom

crossAtomPairTraversed

public void crossAtomPairTraversed(AtomPair pair)

Implement this method to receive notification that a cross AtomPair has been traversed. This is an AtomPair that connects two Atoms in the current layer. Indicates the presence of a cycle with an odd-number of Atoms.

Parameters:

pair - an AtomPair connecting two Atoms in the current layer.
