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

name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
