Detailed Description

template<class TObjectType>
class itk::AutoPointer< TObjectType >

Implements an Automatic Pointer to an object.

AutoPointer is intended to facilitate the construction of objects on the fly for those objects that are not to be shared. An AutoPointer destroys its object when it goes out of scope. Ownership of the object is transferred from one AutoPointer to another AutoPointer when the assignement operator is used. An AutoPointer can release ownership of the object it holds.

This class follows the design of the std::auto_ptr class. The main reason for not using the std version is to avoid templated methods, which greatly increase the difficulty of wrapping for Tcl, Python and Java.

template<class TObjectType>

ObjectType* itk::AutoPointer< TObjectType >::ReleaseOwnership ( void  )

inline

Release the pointer hold by the current AutoPointer and return the raw pointer so it can be hold by another AutoPointer. This operation is intended to be used for facilitating polymorphism.

Example: if class Cow derives from Mammal, AutoPointer<Cow> onecow = new Cow; AutoPointer<Mammal> onemammal = onecow.ReleaseOwnership();

Note that the AutoPointer still points to the object after the ReleaseOwnership operation, but it doesn't own the object any more.
