Method Detail

isWrapperFor

public boolean isWrapperFor(java.lang.Class<?> interfaces)
                     throws java.sql.SQLException

Returns false unless interfaces is implemented

Parameters:

interfaces - a Class defining an interface.

Returns:

true if this implements the interface or directly or indirectly wraps an object that does.

Throws:

java.sql.SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.

unwrap

public <T> T unwrap(java.lang.Class<T> interfaces)
         throws java.sql.SQLException

Returns this if this class implements the interface

Parameters:

interfaces - a Class defining an interface

Returns:

an object that implements the interface

Throws:

java.sql.SQLExption - if no object if found that implements the interface

java.sql.SQLException
