Detailed Description

template<class T, class Container = T>
class FFaSingelton< T, Container >

Template class for singleton classes.

This class is used as a wrapper for classes for which there should only exist one instance. All referencing to the class members are then to be done via the instance() method.

FFaSingelton() [1/2]

template<class T , class Container = T>

FFaSingelton< T, Container >::FFaSingelton ( )

inlineprotected

The constructor is protected to allow objects of sub-classes only.

FFaSingelton() [2/2]

template<class T , class Container = T>

FFaSingelton< T, Container >::FFaSingelton ( const FFaSingelton< T, Container > &  )

protecteddelete

Disable default copy constructor.

Member Function Documentation

allocated()

template<class T , class Container = T>

static bool FFaSingelton< T, Container >::allocated ( )

inlinestatic

Returns true, if the instance has been allocated.

instance()

template<class T , class Container = T>

static T* FFaSingelton< T, Container >::instance ( )

inlinestatic

Returns the actual instance of this class.

The instance is allocated dynamically in the first invocation.

operator=()

template<class T , class Container = T>

FFaSingelton& FFaSingelton< T, Container >::operator= ( const FFaSingelton< T, Container > &  )

protecteddelete

Disable default assignment operator.

removeInstance()

template<class T , class Container = T>

static void FFaSingelton< T, Container >::removeInstance ( )

inlinestatic

Deletes the dynamically allocated instance.

This method is used to clean up memory before terminating.
