isSimple

public boolean isSimple()

Description copied from class: OGCGeometry

Returns true if this geometric object has no anomalous geometric points, such as self intersection or self tangency. See the "Simple feature access - Part 1" document (OGC 06-103r4) for meaning of "simple" for each geometry type. The method has O(n log n) complexity when the input geometry is simple. For non-simple geometries, it terminates immediately when the first issue is encountered.

Overrides:

isSimple in class OGCGeometry

Returns:

True if geometry is simple and false otherwise. Note: If isSimple is true, then isSimpleRelaxed is true too.

makeSimple

public OGCGeometry makeSimple()

makeSimpleRelaxed is not supported for the GeometryCollection instance.

Overrides:

makeSimple in class OGCGeometry

Returns:

Returns simplified geometry. Note: isSimple and isSimpleRelaxed should return true after this operation.

isSimpleRelaxed

public boolean isSimpleRelaxed()

Description copied from class: OGCGeometry

Extension method - checks if geometry is simple for Geodatabase.

Overrides:

isSimpleRelaxed in class OGCGeometry

Returns:

Returns true if geometry is simple, false otherwise. Note: If isSimpleRelaxed is true, then isSimple is either true or false. Geodatabase has more relaxed requirements for simple geometries than OGC.

makeSimpleRelaxed

public OGCGeometry makeSimpleRelaxed(boolean forceProcessing)

makeSimpleRelaxed is not supported for the GeometryCollection instance.

Overrides:

makeSimpleRelaxed in class OGCGeometry

Returns:

Returns simplified geometry. Note: isSimpleRelaxed should return true after this operation.

Specified by:

convertToMulti in class OGCGeometry

Returns:

OGCMulti* or OGCGeometryCollection instance.

reduceFromMulti

public OGCGeometry reduceFromMulti()

Description copied from class: OGCGeometry

For the geometry collection types, when it has 1 or 0 elements, converts a MultiPolygon to Polygon, MultiPoint to Point, MultiLineString to a LineString, and OGCConcretGeometryCollection to the reduced element it contains. If OGCConcretGeometryCollection is empty, returns self.

Specified by:

reduceFromMulti in class OGCGeometry

Returns:

A reduced geometry or this.

public String asJson()

Overrides:

asJson in class OGCGeometry

Returns:

Convert to REST JSON.

isFlattened

public boolean isFlattened()

Checks if collection is flattened.

Returns:

True for the flattened collection. A flattened collection contains up to three non-empty geometries: an OGCMultiPoint, an OGCMultiPolygon, and an OGCMultiLineString.

flatten

public OGCConcreteGeometryCollection flatten()

Flattens Geometry Collection. The result collection contains up to three geometries: an OGCMultiPoint, an OGCMultilineString, and an OGCMultiPolygon (in that order).

Returns:

A flattened Geometry Collection, or self if already flattened.

flattenAndRemoveOverlaps

public OGCConcreteGeometryCollection flattenAndRemoveOverlaps()

Fixes topological overlaps in the GeometryCollecion. This is equivalent to union of the geometry collection elements. TODO "flattened" collection is supposed to contain only mutli-geometries, but this method may return single geometries e.g. for GEOMETRYCOLLECTION (LINESTRING (...)) it returns GEOMETRYCOLLECTION (LINESTRING (...)) and not GEOMETRYCOLLECTION (MULTILINESTRING (...))

Returns:

A geometry collection that is flattened and has no overlapping elements.
