I have this method, that can return three different response.
At first, it was supposed just only return two, so I make its return type to Boolean
like:
public static boolean isLoteWaitingForImage()
And some business logic came out with that it can has another result, so the method was modified to
public static boolean isLoteWaitingForImage() throws ImageNotPendingException
If a certain select
return a null
value, but one row its return true
, if its not null
i will return false
. If no row was acquired from the select
I will throw
an ImageNotPendingException
cause it doesn't apply for the given filters in the where
clause.
Also thought about doing it in this Way, I have this new Class with the types that are valid to return from the method isLoteWaitingForImage()
, with 3 constants properties called:
public class LoteResponse {
public static int VALID = 1;
public static int INVALID = 2;
public static int NO_IMAGE_PENDING = 3;
}
So I will have this new method:
public static int isLoteWaitingForImage() {
return LoteResponse.VALID;
}
Having this on table, I have these two questions:
Any "other" idea about how to accomplish this needing?
Which method is a better practice?
