is a datasource that is not yet exhausted. Exceptions are not necessarily
fatal - the batch might continue depending on the Exception type and the
implementation of the caller.
- Parameters:
context
- the current context passed in by the caller.
- Returns:
- true if there is (or may be) more data to process.
- Throws:
Exception
- if there is a problem with the processing.
