GeoTools介绍

[英]Static methods relative to the global GeoTools configuration. GeoTools can be configured in a system-wide basis through System#getProperties, some of them are declared as String constants in this class.

There are many aspects to the configuration of GeoTools:

  • Default Settings: Are handled as the Hints returned by #getDefaultHints(), the default values can be provided in application code, or specified using system properties.
  • Integration JNDI: Telling the GeoTools library about the facilities of an application, or application container takes several forms. This class provides the #init(InitialContext) method allowing to tell GeoTools about the JNDI context to use.
  • Integration Plugins: If hosting GeoTools in a alternate plugin system such as Spring or OSGi, application may needs to hunt down the FactoryFinders and register additional "Factory Iterators" for GeoTools to search using the #addFactoryIteratorProvidermethod.
    [中]相对于全局GeoTools配置的静态方法。GeoTools可以通过system#getProperties在系统范围内进行配置，其中一些在此类中声明为字符串常量。
    GeoTools的配置有许多方面：
    *默认设置：作为#GetDefaultHitts（）返回的提示处理，默认值可以在应用程序代码中提供，也可以使用系统属性指定。
    *集成JNDI：告诉GeoTools库有关应用程序或应用程序容器的功能有多种形式。此类提供了#init（InitialContext）方法，允许GeoTools了解要使用的JNDI上下文。
    *集成插件：如果在替代插件系统（如Spring或OSGi）中托管GeoTools，则应用程序可能需要查找FactoryFinder，并为GeoTools注册额外的“Factory迭代器”，以便使用#AddFactoryInteratorProviderMethod进行搜索。
