Method Detail

getOpcode

public static DnsMessage.OPCODE getOpcode(int value)
                                   throws IllegalArgumentException

Retrieve the symbolic name of an opcode byte.

Parameters:

value - The byte value of the opcode.

Returns:

The symbolic opcode or null.

Throws:

IllegalArgumentException - If the byte value is not in the range 0..15.

getValue

public byte getValue()

Retrieve the byte value of this opcode.

Returns:

The byte value of this opcode.

valueOf

public static DnsMessage.OPCODE 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

values

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

Returns:

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