Field Detail

esriSR

public SpatialReference esriSR

SpatialReference of the Geometry.

Constructor Detail

OGCGeometry

public OGCGeometry()

Method Detail

dimension

public int dimension()

coordinateDimension

public int coordinateDimension()

geometryType

public abstract java.lang.String geometryType()

estimateMemorySize

public abstract long estimateMemorySize()

Returns an estimate of this object size in bytes.

This estimate doesn't include the size of the SpatialReference object because instances of SpatialReference are expected to be shared among geometry objects.

Returns:

Returns an estimate of this object size in bytes.

SRID

public int SRID()

envelope

public OGCGeometry envelope()

asText

public java.lang.String asText()

asBinary

public java.nio.ByteBuffer asBinary()

asGeoJson

public java.lang.String asGeoJson()

asGeoJsonImpl

java.lang.String asGeoJsonImpl(int export_flags)

asJson

public java.lang.String asJson()

Returns:

Convert to REST JSON.

isEmpty

public boolean isEmpty()

MinZ

public double MinZ()

MaxZ

public double MaxZ()

MinMeasure

public double MinMeasure()

MaxMeasure

public double MaxMeasure()

isSimple

public boolean isSimple()

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.

Returns:

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

isSimpleRelaxed

public boolean isSimpleRelaxed()

Extension method - checks if geometry is simple for Geodatabase.

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

@Deprecated
public OGCGeometry MakeSimpleRelaxed(boolean forceProcessing)

Deprecated.

makeSimpleRelaxed

public OGCGeometry makeSimpleRelaxed(boolean forceProcessing)

Makes a simple geometry for Geodatabase.

Returns:

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

makeSimple

public OGCGeometry makeSimple()

Resolves topological issues in this geometry and makes it Simple according to OGC specification.

Returns:

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

is3D

public boolean is3D()

isMeasured

public boolean isMeasured()

boundary

public abstract OGCGeometry boundary()

Equals

public boolean Equals(OGCGeometry another)

OGC equals. Performs topological comparison with tolerance. This is different from equals(Object), that uses exact comparison.
