# corelinux\_Decorator(3)

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

## NAME

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 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* .RE

**Exceptions:**

*NEVER\_GET\_HERE* .RE

## 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
