Description:

This component provides a single, complex-constrained in-core value-semantic attribute class, bslma::ManagedPtrDeleter, that is used to store a bound function call for a "factory" to destroy an object.

Attributes:

  Name              Type                      Default
  ----------------  ------------------------  -------
  object            void *                    0
  factory           void *                    0
  deleter           void (*)(void *, void *)  0

  Complex Constraints
  ------------------------------------------------------------------
  '0 == deleter' or 'deleter(object, factory)' has defined behavior.

• object Address of the object to be destroyed by the factory.
• factory Address of the factory object that is responsible for destroying object.
• deleter Address of the function that restores the erased types of object and factory, and invokes the factory method to destroy object.
