  • Method Details

    • getType

      public Operator.Type getType()
      Specified by:
      getType in class Operator
    • execute

      public abstract GeometryCursor execute(GeometryCursor geoms, boolean b_merge, ProgressTracker progress_tracker)
      Calculates the convex hull.
      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 abstract Geometry execute(Geometry geom, ProgressTracker progress_tracker)
      Calculates the convex hull geometry.
      Parameters:
      geom - 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 abstract boolean isConvex(Geometry geom, ProgressTracker progress_tracker)
      Checks whether a Geometry is convex.
      Parameters:
      geom - The input geometry to test for convex.
      progress_tracker - The progress tracker.
      Returns:
      Returns true if the geometry is convex.
