void | setMaximumIterations (int n) |
std::vector< SegmentString * > * | getNodedSubstrings () const |
Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent. | |
void | computeNodes (std::vector< SegmentString * > *inputSegmentStrings) |
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.
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.
segStrings | a collection of SegmentStrings to be noded |
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.
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.
n | the maximum number of iterations to perform |
