SqlReturnType (Spring Framework 4.3.30.RELEASE API)

```
public interface SqlReturnType
```
Interface to be implemented for retrieving values for more complex database-specific types not supported by the standard CallableStatement.getObject method.
Implementations perform the actual work of getting the actual values. They must implement the callback method getTypeValue which can throw SQLExceptions that will be caught and translated by the calling code. This callback method has access to the underlying Connection via the given CallableStatement object, if that should be needed to create any database-specific objects.

Object getTypeValue(CallableStatement cs,
                    int paramIndex,
                    int sqlType,
                    String typeName)
             throws SQLException
```
    Get the type value from the specific object.
    Parameters:
    cs - the CallableStatement to operate on
    paramIndex - the index of the parameter for which we need to set the value
    sqlType - SQL type of the parameter we are setting
    typeName - the type name of the parameter
    Returns:
    the target value
    Throws:
    SQLException - if a SQLException is encountered setting parameter values (that is, there's no need to catch SQLException)
