java.lang.Object | +--com.ibm.dse.services.landp.MsreLandp
Magnetic Stripe Reader and Encoder wrapper class. This class communicates with the LANDP MSRE server in order to provide the necessary functionality. Notes: The read() and write() functions cancel any previous one. The RC_IN_PROCESS return code can still be generated, depending on the behavior of the MSRE LANDP server.
