Class Jdbc4NativeJdbcExtractor

java.lang.Object
  org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
      org.springframework.jdbc.support.nativejdbc.Jdbc4NativeJdbcExtractor

All Implemented Interfaces:

NativeJdbcExtractor

public class Jdbc4NativeJdbcExtractor
extends NativeJdbcExtractorAdapter

NativeJdbcExtractor implementation that delegates to JDBC 4.0's unwrap method, as defined by Wrapper.

Note: Only use this when actually running against a JDBC 4.0 driver, with a connection pool that supports the JDBC 4.0 API (i.e. at least accepts JDBC 4.0 API calls and passes them through to the underlying driver)!

Since:

2.5
