本文整理了Java中org.geolatte.geom.codec.Wkb类的一些代码示例，展示了Wkb类的具体用法。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。Wkb类的具体详情如下：
包路径：org.geolatte.geom.codec.Wkb
类名称：Wkb

Wkb介绍

[英]Creates encoders/decoders for WKB geometry representations.

Note that the WkbEncoder/WkbDecoder instances returned by the factory methods are not thread-safe.
[中]为WKB几何体表示创建编码器/解码器。
请注意，工厂方法返回的WkbEncoder/WkbDecoder实例不是线程安全的。
