Enum CdbType

java.lang.Object

java.lang.Enum<CdbType>

org.jscsi.target.scsi.cdb.CdbType

All Implemented Interfaces:

Serializable, Comparable<CdbType>

public enum CdbType
extends Enum<CdbType>

The CdbType determines the length of a serialized CommandDescriptorBlock (CDB) object.

The first 3 bytes (the group code) of the CDB's ScsiOperationCode field specify the CdbType.

Enum Constant Detail

SIX_BYTE_COMMANDS

public static final CdbType SIX_BYTE_COMMANDS

The CDB is 6 bytes long.

TEN_BYTE_COMMANDS

public static final CdbType TEN_BYTE_COMMANDS

The CDB is 10 bytes long.

TWELVE_BYTE_COMMANDS

public static final CdbType TWELVE_BYTE_COMMANDS

The CDB is 12 bytes long.

SIXTEEN_BYTE_COMMANDS

public static final CdbType SIXTEEN_BYTE_COMMANDS

The CDB is 16 bytes long.

VARIABLE_LENGTH_COMMANDS

Method Detail

values

public static CdbType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CdbType c : CdbType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CdbType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getCdbType

public static CdbType getCdbType(ScsiOperationCode scsiOpCode)

Returns the CdbType for the passed ScsiOperationCode.

Parameters:

scsiOpCode - determines CDB length

Returns:

the appropriate CdbType
