Returns an array containing the constants of this enum type, in
the order they are declared. |
Waiting
public static final ReadState Waiting
Complete
public static final ReadState Complete
Error

values
public static ReadState[] 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 (ReadState c : ReadState.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static ReadState 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
