unwrap Method (SQLServerConnectionPoolDataSource)
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
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.
The SQLServerConnectionPoolDataSource class extends the SQLServerDataSource class. When this method is called, the object unwraps to the SQLServerDataSource class and the SQLServerConnectionPoolDataSource class.
