Package io.github.jdbcx

Class WrappedDriver

java.lang.Object

io.github.jdbcx.WrappedDriver

All Implemented Interfaces:

Driver, DriverAction

public class WrappedDriver
extends Object
implements Driver, DriverAction

This class is essentially a wrapper of the Driver interface. It accepts a connection string that starts with jdbcx:, followed by an optional name of a DriverExtension, which defines the default behaviors of the driver. For example, in the JDBC driver, we used to use jdbc:mysql://localhost/test to connect to MySQL. However, now it has changed to jdbcx:mysql://localhost/test or jdbcx:prql:mysql://localhost/test, if you prefer to use PRQL.
