Class TargetPduFactory

java.lang.Object

org.jscsi.target.connection.TargetPduFactory

public class TargetPduFactory
extends Object

A factory class for creating instances of different ProtocolDataUnit types sent by the jSCSI Target.

The static build methods of this class have a parameter for each field and flag of the respective PDU type, except for StatusSN, ExpCmdSN, and MaxCmdSN fields, which are set during the send process (see TargetSenderWorker.sendOverWire(ProtocolDataUnit)).
