Class PmessageJMSv0

java.lang.Object

pygar.communication.PmessageBase

pygar.communication.PmessageJMSv0

All Implemented Interfaces:

java.io.Serializable

@ThreadSafe
public class PmessageJMSv0
extends PmessageBase
implements java.io.Serializable

The PmessageJMSv0 class extends the PmessageBase class to provide a message type with additional fields. Instances of this class can be send as a JMS Message with relatively little effort. This implementation is limited to relatively small files because it allocates a byte buffer to hold the contents of any file that should be sent with the message. A more robust implementation would send the file in blocks with careful attention to potential network errors.

Note that a file body is sent in two fields. A name field holds the name of the file without the path. The path is deleted because it has no general value in a distributed system. Second, the content of the file is contained in a byte array.
