类名称：Hints

Hints介绍

[英]A set of hints providing control on factories to be used. Those hints are typically used by renderers or org.opengis.coverage.processing.GridCoverageProcessor for example. They provides a way to control low-level details. Example:

CoordinateOperationFactory myFactory = &hellip 
Hints hints = new Hints(Hints. 
#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 conjuction with the FactoryRegistry we have the complete geotools plugin system. By using hints to allow application code to effect service discovery we allow client code to retarget the geotools library for their needs.
[中]对要使用的工厂提供控制的一组提示。这些提示通常由渲染器或组织使用。opengis。新闻报道处理。例如GridCoverage处理器。它们提供了一种控制低级细节的方法。例子：

CoordinateOperationFactory myFactory = &hellip 
Hints hints = new Hints(Hints. 
#COORDINATE_OPERATION_FACTORY, myFactory); 
AbstractProcessor processor = new DefaultProcessor(hints);

此类提到的任何提示都被视为API，如果GeoTools工厂实现未能使用提示，则被视为错误（因为它将阻止将此库用于特定于应用程序的任务）。
当提示与FactoryRegistry结合使用时，我们就有了完整的geotools插件系统。通过使用提示允许应用程序代码影响服务发现，我们允许客户端代码根据其需要重新定位geotools库。
