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 >::operator-> (  )  const [inline]

Overload operator ->.

Definition at line 83 of file itkAutoPointer.h.

template<class TObjectType >
bool itk::AutoPointer< TObjectType >::operator< ( const AutoPointer< TObjectType > &  r  )  const [inline]

Comparison of pointers. Less than comparison.

Definition at line 164 of file itkAutoPointer.h.

template<class TObjectType >
bool itk::AutoPointer< TObjectType >::operator<= ( const AutoPointer< TObjectType > &  r  )  const [inline]

Comparison of pointers. Less than or equal to comparison.

Definition at line 172 of file itkAutoPointer.h.

template<class TObjectType >
AutoPointer& itk::AutoPointer< TObjectType >::operator= ( AutoPointer< TObjectType > &  r  )  [inline]

Overload operator assignment.

Definition at line 180 of file itkAutoPointer.h.

template<class TObjectType >
bool itk::AutoPointer< TObjectType >::operator== ( const AutoPointer< TObjectType > &  r  )  const [inline]

Comparison of pointers. Equal comparison.

Definition at line 156 of file itkAutoPointer.h.

template<class TObjectType >
bool itk::AutoPointer< TObjectType >::operator> ( const AutoPointer< TObjectType > &  r  )  const [inline]

Comparison of pointers. Greater than comparison.

Definition at line 168 of file itkAutoPointer.h.

template<class TObjectType >
bool itk::AutoPointer< TObjectType >::operator>= ( const AutoPointer< TObjectType > &  r  )  const [inline]

Comparison of pointers. Greater than or equal to comparison.

Definition at line 176 of file itkAutoPointer.h.

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.

template<class TObjectType >
void itk::AutoPointer< TObjectType >::Reset ( void   )  [inline]

Clear the AutoPointer. If it had a pointer the object is deleted and the pointer is set to null.
