OK
public static final KeeperException.Code OK
Everything is OK
-

values
public static KeeperException.Code[] 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 (KeeperException.Code c : KeeperException.Code.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static KeeperException.Code 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 nameNullPointerException
- if the argument is null
-
intValue
public int intValue()
Get the int value for a particular Code.- Returns:
- error code as integer
-
get
public static KeeperException.Code get(int code)
Get the Code value for a particular integer error code- Parameters:
code
