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.

Member Function Documentation

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.

Definition at line 500 of file object.h.

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.

Definition at line 522 of file object.h.

Here is the call graph for this function:

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.

Definition at line 530 of file object.h.

bool ost::MapIndex::operator== ( const MapObject theObject) const [inline]
