public static final
variable named ERR
with the same type as the subclass; initialize it to an
instance of the subclass. (This is eager singleton
initialization.)
super("foo")

thus: public final ErrorCode

(Note: not ).
ErrorDomain.ErrorCode.withInternalReason(java.lang.String)
, ErrorDomain.ErrorCode.withExtendedHelp(java.lang.String)
, or ErrorDomain.ErrorCode.withSendReport(java.lang.String)
.
Here's a complete example:
public class FooErrorDomain extends ErrorDomain { private FooErrorDomain() { super("Foo"); } public static final FooErrorDomain ERR = new FooErrorDomain(); public final ErrorCode bar = new ErrorCode("brokenBar") .withInternalReason("Bar is not working yet"); public final ErrorCode unsupported = new ErrorCode("unsupported") .withInternalReason("Requested key is not supported"); public final ErrorCode invalid = new ErrorCode("invalidValue") .withInternalReason("Invalid value for attribute") .withExtendedHelp("http://www.google.com/foo/validAttributes.html"); }
Note that all with
methods return a mutated copy.
