Method Detail

dimension

public NumberExpression<Integer> dimension()

The inherent dimension of this geometric object, which must be less than or equal to the coordinate dimension. In non-homogeneous collections, this will return the largest topological dimension of the contained objects.

Returns:

geometryType

public StringExpression geometryType()

Returns the name of the instantiable subtype of Geometry of which this geometric object is an instantiable member. The name of the subtype of Geometry is returned as a string.

Returns:

srid

public NumberExpression<Integer> srid()

Returns the Spatial Reference System ID for this geometric object. This will normally be a foreign key to an index of reference systems stored in either the same or some other datastore.

Returns:

envelope

public GeometryExpression<org.geolatte.geom.Geometry> envelope()

The minimum bounding box for this Geometry, returned as a Geometry. The polygon is defined by the corner points of the bounding box [(MINX, MINY), (MAXX, MINY), (MAXX, MAXY), (MINX, MAXY), (MINX, MINY)]. Minimums for Z and M may be added. The simplest representation of an Envelope is as two direct positions, one containing all the minimums, and another all the maximums. In some cases, this coordinate will be outside the range of validity for the Spatial Reference System.
