Member Functions

Iterate()

status_t Iterate(BShape* shape);

Iterate() iterates over each command that comprises the shape, in order, calling the Iterate…() function that corresponds to each command.

RETURN CODES

B_OK.

No error.

Other errors.

None are defined at this time, but you should always check for errors returned by this function.

IterateBezierTo(), IterateClose(), IterateLineTo(), IterateMoveTo()

virtual status_t IterateBezierTo(int32 bezierCount,
                                 BPoint* bezierPoints);virtual status_t IterateClose();virtual status_t IterateLineTo(int32 lineCount,
                               BPoint* linePoints);virtual status_t IterateMoveTo(BPoint* linePoints);

These functions are called by Iterate() to process the shape commands. Your BShapeIterator-derived class must implement these four functions.
