ObjectScanner.ReusableSet

Enclosing class:

ObjectScanner
```
public static final class ObjectScanner.ReusableSet
extends Object
```
This datastructure keeps track if an object was already put or not atomically. It takes advantage of the fact that each typeflow iteration adds more objects to the set but never removes elements. Since insertions into maps are expensive we keep the map around over multiple iterations and only update the AtomicInteger sequence number after each iteration. Furthermore it also serializes on the object put until the method release is called with this object. So each object goes through two states:
In flight: counter = sequence - 1
Commited: counter = sequence If the object is in state in flight, all other calls with this object to putAndAcquire will block until release with the object is called.
