NAME

       ost::MapIndex -

       The MapIndex allows linear access into a MapTable, that otherwise could have its elements being retrieved only by key.

SYNOPSIS

       #include <object.h>

   Public Member Functions
       MapIndex ()
	   Creates an empty map index (pointing to nothing).
       MapIndex (MapObject *theObject)
	   Creates a map index pointing to a specific map object.
       MapIndex (const MapIndex &theIndex)
	   Creates a copy of a given map index.
       void * operator* () const
	   Dereference operator: the pointed object it is returned as void * for easy re-cast.
       MapIndex & operator= (MapObject *theObject)
	   Assignment operator to avoid implicit cast.
       MapIndex & operator++ ()
	   Prefix increment operator, to be used in loops and such.
       MapIndex operator++ (int)
	   Postfix increment operator, to be used in loops and such.
       bool operator== (const MapIndex &theIndex) const
	   Comparison operator, between two MapIndex's.
       bool operator!= (const MapIndex &theIndex) const
       bool operator== (const MapObject *theObject) const
	   Comparison operator, between the MapIndex and a MapObject, useful to avoid casts for sake of clearness.
       bool operator!= (const MapObject *theObject) const

Detailed Description
       The MapIndex allows linear access into a MapTable, that otherwise could have its elements being retrieved only by key.

       It can be increased, checked and dereferenced like a pointer, by means of suitable operators.

Constructor &; Destructor Documentation
   ost::MapIndex::MapIndex () [inline]
       Creates an empty map index (pointing to nothing).

   ost::MapIndex::MapIndex (MapObject *theObject) [inline]
       Creates a map index pointing to a specific map object. Parameters:
	   the indexed object

   ost::MapIndex::MapIndex (const MapIndex &theIndex) [inline]
       Creates a copy of a given map index. Parameters:
	   the source index object

Member Function Documentation
   bool ost::MapIndex::operator!= (const MapIndex &theIndex) const [inline]
   bool ost::MapIndex::operator!= (const MapObject *theObject) const [inline]
   void* ost::MapIndex::operator* () const [inline]
       Dereference operator: the pointed object it is returned as void * for easy re-cast. Returns:
	   pointer to indexed object.

   MapIndex& ost::MapIndex::operator++ ()
       Prefix increment operator, to be used in loops and such. Returns:
	   the object itself, as changed.

   MapIndex ost::MapIndex::operator++ (int) [inline]
       Postfix increment operator, to be used in loops and such. Returns:
	   the object itself, as changed.

       Referenced by operator++().

   MapIndex& ost::MapIndex::operator= (MapObject *theObject)
       Assignment operator to avoid implicit cast. Returns:
	   the object itself, as changed.

   bool ost::MapIndex::operator== (const MapIndex &theIndex) const [inline]
       Comparison operator, between two MapIndex's. Returns:
	   the object itself, as changed.

   bool ost::MapIndex::operator== (const MapObject *theObject) const [inline]
       Comparison operator, between the MapIndex and a MapObject, useful to avoid casts for sake of clearness. Returns:
	   the object itself, as changed.
