Class OperationFactory

java.lang.Object
org.locationtech.proj4j.geoapi.spi.OperationFactory
All Implemented Interfaces:
org.opengis.referencing.ObjectFactory, org.opengis.referencing.operation.CoordinateOperationFactory, org.opengis.util.Factory
public final class OperationFactory extends Object implements org.opengis.referencing.operation.CoordinateOperationFactory
Registers PROJ4J wrappers as an operation factory.

Future evolution

In a future version, it may not be possible anymore to instantiate this class. For now, we have to allow instantiation for compatibility with Java 8 services. If a future version of PROJ4J migrates to Java 9 module system, the only way to get the factory will by invoking the provider() static method.
