Detailed Description

template<class ReferenceCounter>
class Dune::Fem::ObjectPointer< ReferenceCounter >

models a pointer to a reference countable object

ObjectPointer tries to behave like a normal pointer to an object implementing the ReferenceCounterInterface. Internally, however, it calls the object's addReference and removeReference methods whenever the pointer is created, assign or deleted.

Constructor & Destructor Documentation

ObjectPointer() [1/2]

template<class ReferenceCounter >

Dune::Fem::ObjectPointer< ReferenceCounter >::ObjectPointer ( ReferenceCounterType *const  object = 0 )

inlineexplicit

initialize a pointer (with a standard C++ pointer)

Parameters

[in]

object

C++ pointer to initialize this pointer with; the default value is 0

ObjectPointer() [2/2]

template<class ReferenceCounter >

Dune::Fem::ObjectPointer< ReferenceCounter >::ObjectPointer ( const ThisType &  other )

inline

copy constructor

Copying an ObjectPointer will also increase the reference counter of the object pointed to.

Parameters

[in]

other

pointer to assign to this one

~ObjectPointer()

template<class ReferenceCounter >

Dune::Fem::ObjectPointer< ReferenceCounter >::~ObjectPointer ( )

inline

destructor

When the pointer is deleted, the reference counter of the object pointed to is automatically decreased.

Member Function Documentation

operator*()

template<class ReferenceCounter >

ObjectType& Dune::Fem::ObjectPointer< ReferenceCounter >::operator* ( ) const

inline

dereference the ObjectPointer

Note

This method asserts that the pointer is not 0.

Returns

a reference to the object pointed to.
