isSimplePlanar

protected static int isSimplePlanar(Geometry geometry,
 SpatialReference spatialReference,
 boolean bForce,
 ProgressTracker progressTracker)

The code is executed in the 2D plane only.Attributes are ignored. MultiPoint-check for clustering. Polyline -check for clustering and cracking. Polygon -check for clustering,cracking,absence of self-intersections,and correct ring ordering.

isSimpleAsFeature

protected static int isSimpleAsFeature(Geometry geometry,
 SpatialReference spatialReference,
 boolean bForce,
 NonSimpleResult result,
 ProgressTracker progressTracker)

Checks if Geometry is simple for storing in DB: MultiPoint:check that no points coincide.tolerance is ignored. Polyline:ensure there no segments degenerate segments. Polygon:Same as IsSimplePlanar.

isSimpleOGC

static int isSimpleOGC(Geometry geometry,
 SpatialReference spatialReference,
 boolean bForce,
 NonSimpleResult result,
 ProgressTracker progressTracker)

simplifyAsFeature

protected static Geometry simplifyAsFeature(Geometry geometry,
 SpatialReference spatialReference,
 boolean bForce,
 ProgressTracker progressTracker)

Simplifies geometries for storing in DB: MultiPoint:check that no points coincide.tolerance is ignored. Polyline:ensure there no segments degenerate segments. Polygon:cracks and clusters using cluster tolerance and resolves all self intersections, orients rings properly and arranges the rings in the OGC order. Returns simplified geometry.

simplifyOGC

static Geometry simplifyOGC(Geometry geometry,
 SpatialReference spatialReference,
 boolean bForce,
 ProgressTracker progressTracker)

Simplifies geometries for storing in OGC format: MultiPoint:check that no points coincide.tolerance is ignored. Polyline:ensure there no segments degenerate segments. Polygon:cracks and clusters using cluster tolerance and resolves all self intersections, orients rings properly and arranges the rings in the OGC order. Returns simplified geometry.
