Detailed Description

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

Default Constructor requires a Implementation.

Parameters:
Implementation   instance

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

Copy Constructor copies theImplementation.

Parameters:
Decorator   const reference

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

Gets current theImplementation.

Returns:
Implementation instance

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

Sets current theImplementation to aImplementation.

Parameters:
Implementation   - implementation instance
Exceptions:
Exception   - derivation defined
