Detailed Description

Interface to an polyline and polygon index object managing all non point objects within the datamanager.

Member Function Documentation

virtual double searchGeometry ( int  nnCount, const IPoint &  queryPt, insert_iterator_geometry &  instIt, double  maxDistance = -1  )

pure virtual

k nearest neighbour search

Parameters

[in]	nnCount	number of k neighbour to find
[in]	queryPt	base point for the neighbour search
[in]	instIt	insert iterator for collecting the found geometry objects
[in]	maxDistance	maximum distance (not squared distance) for finding geometry objects (use -1 disabling the distance limit)

Returns

distance to the furthest found geometry object or 'maxDistance' in case on object was found
