isSuccessor method description says:
"Returns true if v1 is a successor of v2 in this graph. Equivalent to v1.getSuccessors().contains(v2)."
Should be:
"Returns true if v2 is a successor of v1 in this graph. Equivalent to v1.getSuccessors().contains(v2)."
Same holds for the return statement and the isPredecessor method
You are quite right. This will be fixed in CVS soon. Thanks!
