Constructor & Destructor Documentation

template<class Implementation> corelinux::Decorator< Implementation >::Decorator (  Implementation    aImplementation )  [inline]

Default Constructor requires a Implementation. Parameters: Implementation  instance

template<class Implementation> corelinux::Decorator< Implementation >::Decorator (  const Decorator< Implementation > &    aDecorator )  [inline]

Copy Constructor copies theImplementation. Parameters: Decorator  const reference

template<class Implementation> corelinux::Decorator< Implementation >::Decorator (  void    )  throw (Assertion) [inline, protected]

Default Constructor Because a Decorator requires a implementation to work, you can not construct one without it. Parameters: void  Exceptions: NEVER_GET_HERE

Member Function Documentation

template<class Implementation> virtual Implementation corelinux::Decorator< Implementation >::getImplementation (  void    )  const [inline, virtual]

Gets current theImplementation. Returns: Implementation instance

template<class Implementation> Decorator& corelinux::Decorator< Implementation >::operator= (  const Decorator< Implementation > &    aDecorator )  throw (Exception) [inline]

Assignment operator overload. This may throw Exception if there is a problem cloning theImplementation. Parameters: Decorator  const reference Returns: Decorator reference to self Exceptions: Exception  - implementation defined

template<class Implementation> bool corelinux::Decorator< Implementation >::operator== (  const Decorator< Implementation > &    aDecorator )  const [inline]

Equality operator overload. Parameters: Decorator  const reference Returns: true if equal, false otherwise

template<class Implementation> virtual void corelinux::Decorator< Implementation >::setImplementation (  Implementation    aImplementation )  throw (Exception) [inline, virtual]

Sets current theImplementation to aImplementation. Parameters: Implementation  - implementation instance Exceptions: Exception  - derivation defined
