Detailed Description

template<class T>
class itk::fem::FEMP< T >

Pointer used to store polymorphic elements in STL arrays.

FEMP holds a pointer to objects of class T and its derived classes. it behaves like a special kind of pointer. Special pointers to object can be used to store polymorphic arrays in STL. The basic idea of the special pointer is: whatever you do to the pointer (object of class FEMP), is also reflected on the object within (pointed to by m_Data member). For example: if you copy the special pointer, an object within is also copied.

Class T should have a member Clone() which produces a copy of an object. This is important in polymorphic classes, where object of the derived class should be created when copying an existing object.

Class T should also include typedefs T::Pointer and T::ConstPointer that define standard pointers to the class. Note that these could be SmartPointer classes.

Constructor & Destructor Documentation

template<class T> itk::fem::FEMP< T >::FEMP (    )  [inline]

Default constructor makes sure that m_Data is 0, to prevent problems when deleting m_Data object on destruction. Definition at line 55 of file itkFEMP.h.

template<class T> itk::fem::FEMP< T >::FEMP (  const FEMP< T > &    x )  [inline]

Copy constructor. Clone() method is called to duplicate the existing object. Definition at line 63 of file itkFEMP.h. References itk::fem::FEMP< T >::m_Data.

template<class T> itk::fem::FEMP< T >::FEMP (  typename T::Pointer    x )  [inline, explicit]

Conversion constructor from T::Pointer to FEMP<T>. The object T* must exist and we take ownership of object T*. If you want to create a copy of object and take ownership of that, use: FEMP(x->Clone()) instead of FEMP(x). Definition at line 76 of file itkFEMP.h.

template<class T> itk::fem::FEMP< T >::~FEMP (    )  [inline]

Destructor of a special pointer class also destroys the actual object. Definition at line 83 of file itkFEMP.h.

Member Function Documentation

template<class T> bool itk::fem::FEMP< T >::IsNULL (    )  const [inline]

Return true if special pointer actually points to a valid object and false otherwise. Definition at line 113 of file itkFEMP.h.

template<class T> itk::fem::FEMP< T >::operator T * (    )  const [inline]

Dereferencing operator provides automatic conversion from special to standard pointer to object Definition at line 104 of file itkFEMP.h.

template<class T> T::Pointer itk::fem::FEMP< T >::operator-> (    )  const [inline]

Easy access to members of stored object Definition at line 98 of file itkFEMP.h.

template<class T> const FEMP< T > & itk::fem::FEMP< T >::operator= (  const FEMP< T > &    rhs )

Asignment operator Definition at line 131 of file itkFEMP.h.
