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

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

This method gets the next group of points.

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

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

This method initializes iterator.

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

bool PointIterator::useSample ( double  x,
double  y,
double  z 
) [inline, protected]
