IMP::WeakPointer< O > Class Template Reference

Detailed Description

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

A weak pointer to an IMP::Object or IMP::RefCountedObject.

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.

Parameters:

[in]

O

The type of IMP::Object-derived object to point to
