Method Summary

void	branchFinished(Atom branch) Implement this method to be notified of the end of a branch traversal starting from branch.
void	branchStarted(Atom branch) Implement this method to be notified of the start of a branch traversal starting from branch.
void	cycleClosureTraversed(AtomPair pair) Implement this method to be notified that pair has been traversed as a cycle closure AtomPair.

Method Detail

branchStarted

public void branchStarted(Atom branch)

Implement this method to be notified of the start of a branch traversal starting from branch. This method will only be invoked after one neighbor of branch has been traversed.

Parameters:

branch - the branch Atom

branchFinished

public void branchFinished(Atom branch)

Implement this method to be notified of the end of a branch traversal starting from branch.

Parameters:

branch - the branch Atom

cycleClosureTraversed

public void cycleClosureTraversed(AtomPair pair)

Implement this method to be notified that pair has been traversed as a cycle closure AtomPair. No notification of the traversal of the same AtomPair via atomPairTraversed will be made, enabling the clear distinction between tree and non-tree AtomPairs.

Parameters:

pair - the AtomPair representing the cycle closure
