Method Detail

execute

public GeometryCursor execute(GeometryCursor geoms,
                              boolean b_merge,
                              ProgressTracker progress_tracker)

Description copied from class: OperatorConvexHull

Calculates the convex hull.

Specified by:

execute in class OperatorConvexHull

Parameters:

geoms - The input geometry cursor.

b_merge - Put true if you want the convex hull of all the geometries in the cursor combined. Put false if you want the convex hull of each geometry in the cursor individually.

progress_tracker - The progress tracker. Allows cancellation of a lengthy operation.

Returns:

Returns a cursor over result convex hulls.

execute

public Geometry execute(Geometry geometry,
                        ProgressTracker progress_tracker)

Description copied from class: OperatorConvexHull

Calculates the convex hull geometry.

Specified by:

execute in class OperatorConvexHull

Parameters:

geometry - The input geometry.

progress_tracker - The progress tracker. Allows cancellation of a lengthy operation.

Returns:

Returns the convex hull. Point - Returns the same point. Envelope - returns the same envelope. MultiPoint - If the point count is one, returns the same multipoint. If the point count is two, returns a polyline of the points. Otherwise, computes and returns the convex hull polygon. Segment - Returns a polyline consisting of the segment. Polyline - If consists of only one segment, returns the same polyline. Otherwise, computes and returns the convex hull polygon. Polygon - If more than one path or if the path isn't already convex, computes and returns the convex hull polygon. Otherwise, returns the same polygon.

isConvex

public boolean isConvex(Geometry geom,
                        ProgressTracker progress_tracker)

Description copied from class: OperatorConvexHull

Checks whether a Geometry is convex.

Specified by:

isConvex in class OperatorConvexHull

Parameters:

geom - The input geometry to test for convex.

progress_tracker - The progress tracker.

Returns:

Returns true if the geometry is convex.
