BaseURLStore (sql2java-stor 3.0.0 API)

java.lang.Object
- gu.sql2java.store.BaseURLStore

All Implemented Interfaces:

URLStore, java.net.URLStreamHandlerFactory

Direct Known Subclasses:

LocalBinaryStore
```
public abstract class BaseURLStore
extends java.lang.Object
implements java.net.URLStreamHandlerFactory, URLStore
```
基于URLStreamHandler实现二进制存储接口URLStore的抽象类
实现URLStreamHandlerFactory接口,应用启动时应调用intall()将当前实例安装到JVM
