程序包 gu.sql2java.geometry

类 GeometryDataCodec

java.lang.Object
gu.sql2java.geometry.GeometryDataCodec
所有已实现的接口:
com.vividsolutions.jts.io.WKBConstants
直接已知子类:
MysqlGeometryDataCodec
public class GeometryDataCodec extends Object implements com.vividsolutions.jts.io.WKBConstants
存储格式WKB,WKT与Geometry对象之间的互相转换实现基类, 对于不同的数据库，应该继承此类根据数据库存储WKB方式的不同提供合适的实现
子类必须实现toWKB(Object),fromWKB(byte[]),getGeomtyColumnTypes()方法, 否则toWKB(Object),fromWKB(byte[])总是返回null, getGeomtyColumnTypes()方法总是返回空
从以下版本开始:
3.18.0
