org.geotools.factory.Hints
A set of hints providing control on factories to be used. Those hints are typically used by renderers or {@linkplain org.opengis.coverage.processing.GridCoverageProcessor grid coverageprocessors} for example. They provides a way to control low-level details. Example:
```
 CoordinateOperationFactory myFactory = &hellip Hints hints = new Hints(Hints. {@linkplain #COORDINATE_OPERATION_FACTORY}, myFactory); AbstractProcessor processor = new DefaultProcessor(hints); 
```
Any hint mentioned by this class is considered to be API, failure to make use of a hint by a GeoTools factory implementation is considered a bug (as it will prevent the use of this library for application specific tasks).
When hints are used in conjunction with the {@linkplain FactoryRegistry factory servicediscovery mechanism} we have the complete geotools plugin system. By using hints toallow application code to effect service discovery we allow client code to retarget the geotools library for their needs. @since 2.1 @source $URL$ @version $Id$ @author Martin Desruisseaux @author Jody Garnett

Hints that guice created dependencies can accept on their constructors, contains flags to enable/disable operational modes on databases. In the future may provide other kind of hints to other components. @see ContextBuilder#build(Hints)
