Returns:

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

valueOf

public static MessageType valueOf(String name)

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

Parameters:

code - the byte code from the wire

Returns:

the matching MessageType

Throws:

IllegalArgumentException - if the code is unrecognized

getCode

public byte getCode()

Returns the byte code corresponding to this message type.

Returns:

the D-Bus message type code
