Class TaintSet

java.lang.Object
ghidra.taint.model.TaintSet
public class TaintSet extends Object
An immutable set of multiple taint marks

A variable in an emulator could be tainted by multiple marks, so we must use vectors of sets, not vectors of marks. Please see TaintMark.equals(Object) regarding the equality of tagged marks.
