    Soft Pointers

    A soft pointer is simply a pointer to an object. It does not protect the referenced object from purge.

    Examples of soft pointer references

    • Xdata references are soft pointers.
    • Persistent reactors are soft pointers.

    If you use a soft pointer to refer to an object, you should check that the object still exists before you open it.
