12.10 ISInfoDocument::Iterator

#include <is/infodocument.h>

IPCPartition p ( "MyPartition" );

ISInfoDocument::Iterator it ( p );

This class allows sequential access to all the available IS meta-types.

Iterator( IPCPartition & p );

Constructs a new ISInfoDocument::Iterator instance in the p partition.

Iterator( const Iterator & i );

Copy constructor.

Iterator &

operator=(const Iterator & i);

Copy operator.

bool

operator()();

Returns true if the current iterator's position is valid, false otherwise.

operator bool();

Returns true if the current iterator's position is valid, false otherwise.

const ISInfoDocument &

operator*();

Returns reference to the ISInfoDocument object at the current iterator's position.

const Iterator 

operator++();

Prefix increment. Advances iterator to the next position and returns the copy of the iterator object. The iterator, which is returned points to the new position.

const Iterator &

operator++( int );

Postfix increment. Returns copy of the iterator and advances iterator to the next position. The iterator, which is returned points to the old position.

const Iterator 

operator--();

Prefix decrement. Moves iterator to the previous position and returns the copy of the iterator object. The iterator, which is returned points to the new position.

const Iterator &

operator--( int );

Postfix decrement. Returns copy of the iterator and moves iterator to the previous position. The iterator, which is returned points to the old position.

size_t

size();

Returns number of ISInfoDocument objects in the iterator.
