Detailed Description

The PointIterator class is the base class for accessing the point data in a PointSource. Use PointSource::createIterator() to create a iterator.

See examples/src/UserTutorial.cpp for an example of using a PointIterator.

Member Function Documentation

§ getNextPoints()

virtual size_t PointIterator::getNextPoints ( PointData points)
pure virtual

This method gets the next group of points.

Parameters
pointsthe destination buffer
Returns
the number points written in the buffer

§ init()

void PointIterator::init ( const Bounds bounds,
double  fraction,
const PointInfo pointInfo,
ProgressDelegate delegate 
)
protected

This method initializes iterator.

Parameters
boundsthe region of interest (HUGE_VAL are handled)
fractionthe fraction of the points you want (use 1.0 for all the points and use 0.1 to keep every tenth point)
pointInfothe list of channels to be extracted
delegatea ProgressDelegate for feedback (can be NULL)
Note
init() should have the same prototype a PointSource::createIterator()

§ useSample()

bool PointIterator::useSample ( double  x,
double  y,
double  z 
)
