unwrap Method (SQLServerDataSource)

  • Article

Download JDBC driver

Returns an object that implements the specified interface to allow access to the Microsoft JDBC Driver for SQL Server-specific methods.

Syntax

  
public <T> T unwrap(Class<T> iface)

Parameters

iface

A class of type T defining an interface.

Return Value

An object that implements the specified interface.

Exceptions

SQLServerException

Remarks

The unwrap method is defined by the java.sql.Wrapper interface, which is introduced in the JDBC 4.0 Spec.

Applications might need to access extensions to the JDBC API that are specific to the Microsoft JDBC Driver for SQL Server. The unwrap method supports unwrapping to public classes that this object extends if the classes expose vendor extensions.

When this method is called, the object unwraps to the SQLServerDataSource class.

For more information, see Wrappers and Interfaces.
