Detailed Description

Nodes a set of SegmentStrings completely. The set of segmentStrings is fully noded; i.e. noding is repeated until no further intersections are detected.

Iterated noding using a FLOATING precision model is not guaranteed to converge, due to roundoff error. This problem is detected and an exception is thrown. Clients can choose to rerun the noding using a lower precision model.

Last port: noding/IteratedNoder.java rev. 1.6 (JTS-1.7)

Member Function Documentation

void geos::noding::IteratedNoder::computeNodes (  std::vector< SegmentString * > *  inputSegmentStrings  )  [virtual]

Fully nodes a list of SegmentStrings, i.e. peforms noding iteratively until no intersections are found between segments. Maintains labelling of edges correctly through the noding. Parameters: segStrings  a collection of SegmentStrings to be noded Exceptions: TopologyException  if the iterated noding fails to converge. Implements geos::noding::Noder.

std::vector<SegmentString*>* geos::noding::IteratedNoder::getNodedSubstrings (   )  const [inline, virtual]

Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent. Returns: a newly allocated std::vector of const SegmentStrings. Caller is responsible to delete it Implements geos::noding::Noder.

void geos::noding::IteratedNoder::setMaximumIterations (  int  n  )  [inline]

Sets the maximum number of noding iterations performed before the noding is aborted. Experience suggests that this should rarely need to be changed from the default. The default is MAX_ITER. Parameters: n  the maximum number of iterations to perform
