Class ToppedSet

java.lang.Object

soot.toolkits.scalar.AbstractFlowSet

soot.jimple.toolkits.scalar.ToppedSet

All Implemented Interfaces:

java.lang.Iterable, FlowSet

public class ToppedSet
extends AbstractFlowSet

Represents information for flow analysis, adding a top element to a lattice. A FlowSet is an element of a lattice; this lattice might be described by a FlowUniverse. If add, remove, size, isEmpty, toList and contains are implemented, the lattice must be the powerset of some set.
