  java.lang.Enum<TapOpcode>
      net.spy.memcached.tapmessage.TapOpcode

All Implemented Interfaces:

Serializable, Comparable<TapOpcode>

public enum TapOpcode
extends Enum<TapOpcode>

The Opcode enum contains a list all of the different opcodes that can be passed in a tap message in the flag field.

Method Detail

values

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

Returns:

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

valueOf

public static TapOpcode 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

getOpcodeByByte

public static TapOpcode getOpcodeByByte(byte b)
