	Computes the noding for a collection of SegmentStrings.
void	validate ()
std::vector< SegmentString * > *	getNodedSubstrings () const override
	Returns a collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Detailed Description

A wrapper for noding::Noders which validates the output arrangement is correctly noded. An arrangement of line segments is fully noded if there is no line segment which has another segment intersecting its interior. If the noding is not correct, a util::TopologyException is thrown with details of the first invalid location found.

Member Function Documentation

computeNodes()

void geos::noding::ValidatingNoder::computeNodes ( std::vector< SegmentString * > *  segStrings )

overridevirtual

Computes the noding for a collection of SegmentStrings.

Some Noders may add all these nodes to the input SegmentStrings; others may only add some or none at all.

Parameters

segStrings

a collection of SegmentStrings to node The caller remains responsible for releasing the memory associated with the container and its elements.

Implements geos::noding::Noder.

getNodedSubstrings()

std::vector< SegmentString * > * geos::noding::ValidatingNoder::getNodedSubstrings ( ) const

overridevirtual

Returns a collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Returns

a newly allocated std::vector of newly allocated SegmentStrings (copies of input, if needs be). Caller is responsible to delete container and elements.

Implements geos::noding::Noder.
