Class MemoryExecutionHistory

java.lang.Object
  net.sf.mybatchfwk.history.MemoryExecutionHistory

All Implemented Interfaces:

IExecutionHistory

public class MemoryExecutionHistory
extends java.lang.Object
implements IExecutionHistory

This implementation store the ids into the memory.
Warning:
- the number of ids stored must be very limited, in order to prevents OutOfMemoryError.
- there is no persistence, so the ids are lost when the batch is stopped.
