Detailed Description

template<class O>
struct IMP::WeakPointer< O >

Smart pointer to Object-derived classes that does not refcount.

WeakPointers do not do reference counting and do not claim ownership of the pointed object. As a result, they can be used to break cycles in reference counted pointers. For example, since an IMP::Model contains a reference counted pointer to an IMP::Particle, the IMP::Particle has a WeakPointer back to the Model.

This version of a WeakPointer only works on complete types, but adds additional checks of correct usage (eg that the Object has not been previously freed) compared to UncheckedWeakPointer.
