    Interface for Memoable objects. Memoable objects allow the taking of a snapshot of their internal state via the copy() method and then reseting the object back to that state later using the reset() method.
    • Method Detail

      • copy

        Memoable copy()
        Produce a copy of this object with its configuration and in its current state.

        The returned object may be used simply to store the state, or may be used as a similar object starting from the copied state.

      • reset

        void reset​(Memoable other)
        Restore a copied object state into this object.

        Implementations of this method should try to avoid or minimise memory allocation to perform the reset.

        Parameters:
        other - an object originally copied from an object of the same type as this instance.
        Throws:
        ClassCastException - if the provided object is not of the correct type.
