public class SpatialContextFactory extends Object
SpatialContext
based on configuration data. Call
makeSpatialContext(java.util.Map, ClassLoader)
to construct one via String name-value
pairs. To construct one via code then create a factory instance, set the fields, then call
newSpatialContext()
.
The following keys are looked up in the args map:
SpatialContext.isGeo()
DistanceCalculator
ENVELOPE(xMin, xMax, yMax, yMin)
-- see SpatialContext.getWorldBounds()
SpatialContext.isNormWrapLongitude()

Creates a new

args . |

makeWktShapeParser(SpatialContext ctx) |

newSpatialContext()
Subclasses should simply construct the instance from the initialized configuration.

in it.
The factory class is looked up via "spatialContextFactory" in args
then falling back to a Java system property (with initial caps). If neither are specified
then SpatialContextFactory
is chosen.args
