Method Detail

createGeometry

public Geometry createGeometry(java.lang.String type,
                               Envelope envelope,
                               double[] xy,
                               double[] z,
                               double[] m,
                               int[] partOffsets,
                               int[] subPartOffsets,
                               double length,
                               double area)
                        throws java.lang.ClassNotFoundException

Creates a geometry object from all the arguments. In case of illegal or null envelope, length, area, the particular geometry construction may ignore or attempt to calculate these values.

In order to create an empty geometry, xy must be null or a zero length array. In this case, the geometry has a "z" subtype iff z is not null, and has a "m" subtype iff m is not null.

Parameters:

type - the type of the geometry to be created

envelope - the envelope of the geometry to be created

xy - array of xy coordinate pairs; if null or of length equal to zero, an empty geometry will be created

z - array of z coordinate pairs; if null, the geometry created will not have z coordinates

m - array of m values; if null, the geometry created will not have measure values

partOffsets - array holding positions in the xy coordinate array where geometry parts start. This argument is required for MultiLineString, Polygon, and MultiPolygon geometries.

subPartOffsets - array holding positions in the xy coordinate array where geometry subparts start. This argument is required for Polygon and MultiPolygon geometries.

length - the length of the geometry to be created

area - the area of the geometry to be created

Returns:

a geometry object

Throws:

java.lang.ClassNotFoundException - in case type is not an instantiable type from the package com.ibm.spatial.geom.
