Examples of com.spatial4j.core.context.SpatialContext

com.spatial4j.core.context.SpatialContext
This is a facade to most of Spatial4j, holding things like {@link DistanceCalculator}, {@link com.spatial4j.core.io.WktShapeParser}, and acting as a factory for the {@link Shape}s.
If you want a typical geodetic context, just reference {@link #GEO}. Otherwise, You should either create and configure a {@link SpatialContextFactory} and then call{@link SpatialContextFactory#newSpatialContext()}, OR, call {@link com.spatial4j.core.context.SpatialContextFactory#makeSpatialContext(java.util.Map,ClassLoader)}to do this via configuration data.
Thread-safe & immutable.
