Examples of org.apache.derby.iapi.error.StandardException

org.apache.derby.iapi.error.StandardException
StandardException is the root of all exceptions that are handled in a standard fashion by the database code, mainly in the language code.
This class is abstract to ensure that an implementation only throws a specific exception (e.g. TransactionException) which is a sub-class
A method in an iterface in a protocol under com.ibm.db2j.protocol.Database must only throw a StandardException (if it needs to throw an exception). This indicates that the method can throw an exception and therefore its caller must ensure that any resources it allocates will be cleaned up in the event of an exception in the StandardException hierarchy.
Implementations of methods that throw StandardException can have throws clause that are more specific than StandardException.
