Method Detail

getback to summary
public ArrayList<LivenessPathElement> get(Oop obj)

Returns an ArrayList of the incoming references to this Oop if it is alive, and null if it is dead according to the ReversePtrsAnalysis. Currently not all roots are scanned so this result is frequently inaccurate for JVM-internal objects, but is usually correct for Java-level objects.
