Detailed Description

template<typename objectType, template< class > class ownershipPolicy = InternalRefCounted, template< class > class destroyPolicy = DefaultDestroyPolicy>
class cxxtools::SmartPtr< objectType, ownershipPolicy, destroyPolicy >

Policy-based smart-pointer-class.

This class works like a pointer, but the destructor deletes the held object if this is the last reference. The policy specifies, how the class counts the references. There are 4 policies:

ExternalRefCounted: allocates a reference-count

ExternalAtomicRefCounted: like ExternalRefCounted, but thread safe

InternalRefCounted: the pointed object needs to have a reference-counter with methods addRef() and release(). The release-method deletes the object, when the reference-count drops to 0.

RefLinked: all pointers to a object are linked

The default policy is InternalRefCounted. Another class cxxtools::RefCounted implements proper methods for the pointer, which makes it straight-forward to use.
