NAME

Geo::Geos::Noding::SingleInteriorIntersectionFinder - inds an interior intersection in a set of SegmentString, if one exists.

SYNOPSIS

    use Geo::Geos::Coordinate;
    use Geo::Geos::PrecisionModel;
    use Geo::Geos::Noding::BasicSegmentString;
    use Geo::Geos::Noding::IntersectionAdder;

    my $c1 = Geo::Geos::Coordinate->new(0,1);
    my $c2 = Geo::Geos::Coordinate->new(1,1);

    my $c2_2 = Geo::Geos::Coordinate->new(1,0);
    my $c2_1 = Geo::Geos::Coordinate->new(1,2);
    my $pm = Geo::Geos::PrecisionModel->new;

    my $ss1 = Geo::Geos::Noding::BasicSegmentString->new([$c1, $c2]);
    my $ss2 = Geo::Geos::Noding::BasicSegmentString->new([$c2_1, $c2_2]);

    my $li = Geo::Geos::Algorithm::LineIntersector->new($pm);

    my $sid = Geo::Geos::Noding::SingleInteriorIntersectionFinder->new($li); # => isa 'Geo::Geos::Noding::SingleInteriorIntersectionFinder'
    Geo::Geos::Noding::SingleInteriorIntersectionFinder->new($li);           # => isa 'Geo::Geos::Noding::SegmentIntersector'

    $sid->isDone;   # => ''

    $sid->processIntersections($ss1, 0, $ss2, 0);
    my $r1 = $sid->isDone;              # => success
    my $r2 = $sid->hasIntersection;     # => success

    my $c = $sid->getInteriorIntersection;  # => is Geo::Geos::Coordinate->new(1, 1)
    $sid->getIntersectionSegments->[0];     # => isa 'Geo::Geos::Coordinate'
