SCSICommand

SCSICommand encapsulates generic functinality that is needed for each SCSI command that can be sent to a device. All new commands must implement this abstract class, ensure to call init_cdb, and override the unmarshall function.

abstract

class SCSICommand {

ubyte[] sense [@property getter];

ubyte[] dataout [@property getter];

ubyte[] datain [@property getter];

ubyte[] cdb [@property getter];

SCSIDevice device [@property getter];

this(SCSIDevice dev, ubyte opcode, int dataout_alloclen, int datain_alloclen);

~this();

void init_cdb(ubyte opcode);

void execute();

void unmarshall();

}

Constructors

this this(SCSIDevice dev, ubyte opcode, int dataout_alloclen, int datain_alloclen): The constructor will allocate sense, dataout, and datain buffers as necessary

Destructor

~this ~this(): Undocumented in source.

Members

Functions

execute void execute(): Execute the SCSI command on the device (using device.sgio_execute), then unmarshalls the datain buffer with a call to unmarshall().
init_cdb void init_cdb(ubyte opcode): Allocate the CDB and set the opcode field. Opcode is used to determine cdb length.
unmarshall void unmarshall(): Abstract method used to unmarshall the datain buffer.

Properties

cdb ubyte[] cdb [@property getter]: Get a reference ot the CDB
datain ubyte[] datain [@property getter]: Get a reference to the datain buffer (possibly null)
dataout ubyte[] dataout [@property getter]: Get a reference to the dataout buffer (possibly null)
device SCSIDevice device [@property getter]: Get the SCSIDevice
sense ubyte[] sense [@property getter]: Get a reference to the sense buffer

Variables

m_cdb ubyte[] m_cdb;: Undocumented in source.
m_dataout ubyte[] m_dataout;: Undocumented in source.
