    Method
    Description
    boolean
    hasExceptionalEdge(T src, T dst)
    This method must return true if and only if an exceptional edge from src to dst exists in the original CFG and should be kept for the pruned version of that CFG.

      Description copied from interface: EdgeFilter
      This method must return true if and only if an exceptional edge from src to dst exists in the original CFG and should be kept for the pruned version of that CFG. Note that this must _must_ return false for any exceptional edge that is not in the original CFG.
