Check parameters annotated with @Nonnull for null?
We’ve begun using FindBugs and annotating our parameters with @Nonnull
appropriately, and it works great to point out bugs early in the cycle. So far we have continued checking these arguments for null
using Guava’s checkNotNull
, but I would prefer to check for null
only at the edges–places where the value can come in without having been checked for null
, e.g., a SOAP request.
AND is better or using Internal “IF” [duplicate]
This question already has answers here: Is it bad practice to use short-circuit evaluation instead of an if clause? [duplicate] (7 answers) Closed 9 years ago. In a situation like this:” if ((metadata != null) && (metadata.TypeEnum != VariantInfoMetadata.CellTypeEnum.Status)) do you recommend to keep the code as it is above? Or is it better to […]

Summary:
Requiring Explicit Null Reference Handling
One of the problems I have with null references is that they may not be exceptional. In my current position, there are few requirements and you are lucky if conventions are followed. This means being unable to handle a request is a frequent occurrence and throwing an exception is too slow (think millions of requests). I am in charge of writing an api for handling these requests and I am trying to decide how to handle failures.
Does ‘consider returning Null Object’ apply to a DAO read method?
I was looking for an answer to the question of what a DAO should return when a search ends up to be for an entity that does not exist.
design strategy pattern with null checking
When the context class can accept a null strategy, is there another way to do it without check if its null?
Is it good practice to not filter values according to nullability?
Sometimes when I create an API that should enable getting a single value or all values I use the following pattern (passing NULL
to the API, means get all rows):
