包路径：org.opengis.filter.FilterFactory2
类名称：FilterFactory2

FilterFactory2介绍

[英]Allows creation of additional Filter constructs.

Why do we need this? Because not all implementations are going to be using geoapi Geometry. This allows the creation of complient filters with SFSQL Geometry constructs. Consider this a bridge to existing projects allowing GeoAPI to be used.
[中]允许创建其他筛选器构造。
我们为什么需要这个？因为并非所有的实现都将使用geoapi几何体。这允许使用SFSQL几何结构创建complient筛选器。认为这是一个桥梁，以允许使用GEOAPI的现有项目。
