Detailed Description

template<class Implementation> template class corelinux::Decorator

Decorators can attach additional responsibilities to an object dynamically which provide a more flexible alternative to subclassing for extending functionality.

Constructor & Destructor Documentation

template<classImplementation> corelinux::Decorator<Implementation>::Decorator<Implementation> ( Implementation aImplementation )

Default Constructor requires a Implementation. Parameters: Implementation   instance

template<classImplementation> corelinux::Decorator<Implementation>::Decorator<Implementation> ( const Decorator<Implementation> & aDecorator )

Copy Constructor copies theImplementation. Parameters: Decorator   const reference

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

Gets current theImplementation. Returns: Implementation instance

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

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