Specified by:
materializeObject in interface ExtendedType
Specified by:
materializeObject in class AbstractType
Throws:
java.lang.Exception - if read error ocurred, or an object can't be converted to a target Java class.

materializeObject

public java.lang.Object materializeObject(java.sql.CallableStatement cs,
                                          int index,

                   throws java.lang.Exception
Description copied from class: AbstractType
Calls "PreparedStatement.setObject(..)". Some DbAdapters may need to override this behavior for at least some of the object types, as it doesn't work consistently across all JDBC drivers.

Specified by:
setJdbcObject in interface ExtendedType
Overrides:
setJdbcObject in class AbstractType
Throws:
java.lang.Exception
