public class EdgeIntersectionList
extends java.lang.Object
A list of edge intersections along an Edge
EdgeIntersection | add(Coordinate intPt, int segmentIndex, double dist) - Adds an intersection into the list, if it isn't already there.

void | addEndpoints() - Adds entries for the first and last points of the edge to the list

void | addSplitEdges(List edgeList) - Creates new edges for all the edges that the intersections in this
list split the parent edge into.

boolean | isIntersection(Coordinate pt) - This routine searches the list for the insertion point for the given intersection
(which must be in normalized form).

EdgeIntersectionList
public EdgeIntersectionList(Edge edge)
add
public EdgeIntersection add(Coordinate intPt,
int segmentIndex,
double dist)
Adds an intersection into the list, if it isn't already there.
The input segmentIndex and dist are expected to be normalized.
- the EdgeIntersection found or added
addEndpoints
public void addEndpoints()
Adds entries for the first and last points of the edge to the list
addSplitEdges
public void addSplitEdges(List edgeList)
Creates new edges for all the edges that the intersections in this
list split the parent edge into.
Adds the edges to the input list (this is so a single list
can be used to accumulate all split edges for a Geometry).
isIntersection
public boolean isIntersection(Coordinate pt)
This routine searches the list for the insertion point for the given intersection
(which must be in normalized form).
The intersection point may already be in the list - in this case, the intersection
is not inserted.
If the intersection is new, it is inserted into the list.
The insertIt iterator is left pointing at the correct place
to insert the intersection, if the intersection was not found.
- true if this intersection is already in the list
iterator
public Iterator iterator()
returns an iterator of EdgeIntersections
print
public void print(PrintStream out)
