Detailed Description

Whenever the du-chain is unlocked and locked again, any du-chain item may have been deleted in between.

For that reason, the following class should be used to make sure that no deleted objects are accessed. It contains a pointer that will be reset to zero once the pointed object is deleted.

Access to the data must still be serialized through duchain-locking. Using this comes with no additional cost.

In practice this means: Store an instance of DUChainPointer instead of a pointer to the du-chain object. Then, access the eventually still existing object by calling pointer->base().

To make it even more convenient see DUChainPointer
