Enum AddressMethod

java.lang.Object

java.lang.Enum<AddressMethod>

org.jscsi.target.scsi.lun.AddressMethod

All Implemented Interfaces:

Serializable, Comparable<AddressMethod>

public enum AddressMethod
extends Enum<AddressMethod>

The ADDRESS METHOD field of a LOGICAL UNIT NUMBER's ADDRESSING field (from FIRST LEVEL ADDRESSING to FOURTH LEVEL ADDRESSING) defines the contents of the ADDRESS METHOD SPECIFIC field.

This field is two bits long.

Enum Constant Detail

PERIPHERAL_DEVICE_ADDRESSING_METHOD

public static final AddressMethod PERIPHERAL_DEVICE_ADDRESSING_METHOD

The SCSI target device should relay the received command or task management function to the addressed dependent logical unit.

FLAT_SPACE_ADDRESSING_METHOD

public static final AddressMethod FLAT_SPACE_ADDRESSING_METHOD

The flat space addressing method specifies a logical unit at the current level. The contents of all hierarchical structure addressing fields following a flat space addressing method addressing field shall be ignored.

LOGICAL_UNIT_ADDRESSING_METHOD

public static final AddressMethod LOGICAL_UNIT_ADDRESSING_METHOD

The SCSI device should relay the received command or task management function to the addressed dependent logical unit.

EXTENDED_LOGICAL_UNIT__ADDRESSING_METHOD

public static final AddressMethod EXTENDED_LOGICAL_UNIT__ADDRESSING_METHOD

Extended logical unit addressing specifies a logical unit at the current level.

Extended logical unit addressing builds on the formats defined for dependent logical units (see 4.6.19.4) but may be used by SCSI devices having single level logical unit structure. In dependent logical unit addressing, the logical unit information at each level fits in exactly two bytes. Extended logical unit addresses have sizes of two bytes, four bytes, six bytes, or eight bytes.

Method Detail

values

public static AddressMethod[] 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 (AddressMethod c : AddressMethod.values())
    System.out.println(c);

Returns:

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

valueOf

public static AddressMethod 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

getValue

public byte getValue()

Returns the serialized value of the object.

Returns:

the serialized value of the object

getValue

public static AddressMethod getValue(int value)

Returns the AddressMethod with a matching value or null if no such AddressMethod exists.

Parameters:

value - the value from a serialized ADDRESS METHOD field

Returns:

the AddressMethod with a matching value or or null
