    Main uses of IdentityHashMap are:

    1. Topology Preservation: The typical use of

    IdentityHashMap class is topology-preserving object

    graph transformations, such as serialization or deepcopying. In such a scenario, a program must maintain a

    "node table" to keep track of all the object references that

    have already been processed.

    2. The node table should not considered distinct objects as

    equal even if they happen to be equal.

    3. Proxy objects: Another use of this class is to maintain

    proxy objects. A debugging program has to maintain a

    proxy object for each object in the program being

    debugged.
