GeometryFactory.createMultiPolygon介绍

[英]Creates a MultiPolygon using the given Polygons; a null or empty array will create an empty Polygon. The polygons must conform to the assertions specified in the OpenGIS Simple Features Specification for SQL.
[中]使用给定多边形创建多多边形；空数组或空数组将创建空多边形。多边形必须符合OpenGIS Simple Features Specification for SQL中指定的断言。
