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.
