template< class TypeImpl > class corelinux::Singleton: public CoreLinuxObject

Ensure a class only has one instance, and provide a global point of access to it.

Inheritance:

Public Methods
Singleton( void ) throw( Assertion ): Default constructor sets theSingleton and theType after insuring that they are not already instantiated
Singleton( TypeImpl *aTypePtr ) throw( Assertion ): Initializing constructor
static TypeImpl* instance( void ): Returns the instance of the TypeImpl
bool operator==( const Singleton & aSingleton ) const: Equality operator tests that theSingleton instances are equal
virtual ~Singleton( void ): Virtual destructor

Inherited from CoreLinuxObject:

Public Methods
bool operator!=( CoreLinuxObjectCref ) const
CoreLinuxObjectRef operator=( CoreLinuxObjectCref )

Documentation

Ensure a class only has one instance, and provide a global point of access to it. This is easier said than done outside of the solution domain. While we can declare a protocol by which the use of this type will prevent multiple applications, we can't insure that the implementor won't violate said protocol.

Singleton( void ) throw( Assertion )

Default constructor sets theSingleton and theType after insuring that they are not already instantiated
