Enum Constant Detail
public static final WebSocketState OPENThe WebSocket connection is established (= the opening handshake has succeeded) and usable.
public static WebSocketState 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 (WebSocketState c : WebSocketState.values()) System.out.println(c);
- an array containing the constants of this enum type, in the order they are declared
public static WebSocketState valueOf(java.lang.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.)
name- the name of the enum constant to be returned.
- the enum constant with the specified name
java.lang.IllegalArgumentException- if this enum type has no constant with the specified name
java.lang.NullPointerException- if the argument is null
