本文整理了Java中org.geotools.util.factory.GeoTools.getDefaultHints()方法的一些代码示例，展示了GeoTools.getDefaultHints()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。GeoTools.getDefaultHints()方法的具体详情如下：
包路径：org.geotools.util.factory.GeoTools
类名称：GeoTools
方法名：getDefaultHints

GeoTools.getDefaultHints介绍

[英]Returns the default set of hints used for the various utility classes. This default set is determined by:

  • The System#getProperties system properties available. Some property keys are enumerated in the GeoTools class.
  • Any hints added by call to the Hints#putSystemDefault or #init method.

Long term plan: We would like to transition the utility classes to being injected with their required factories, either by taking Hints as part of their constructor, or otherwise. Making this change would be a three step process 1) create instance methods for each static final class method 2) create an singleton instance of the class 3) change each static final class method into a call to the singleton. With this in place we could then encourage client code to make use of utility class instances before eventually retiring the static final methods.
[中]返回用于各种实用程序类的默认提示集。此默认设置由以下因素确定：
*系统#getProperties系统属性可用。某些属性键在GeoTools类中枚举。
*通过调用hints#putSystemDefault或#init方法添加的任何提示。
长期计划：我们希望通过将提示作为构造函数的一部分或其他方式，将实用程序类转换为注入它们所需的工厂。进行此更改需要三个步骤：1）为每个静态最终类方法创建实例方法2）创建类的单例实例3）将每个静态最终类方法更改为对单例的调用。这样，我们就可以鼓励客户机代码在最终停用静态final方法之前使用实用程序类实例。
