> As we all know, Groovy is a powerful language with great built-in functions. Groovy Truth[1]
is one of them, which is not used properly in our code base. We have used UtilValidate Class
to validate arguments for Empty or NotEmpty, which can easily be done in groovy with built-in
functionality.
>  
> Current Code: if (UtilValidate.isNotEmpty(locations)) \{ ... }
>  
> Groovy Built-in Code: if (locations) \{ ... }
>  
> IMO, We should use this Groovy Truth feature instead of UtilValidate Class. Please let
me know your thoughts on this. Thanks!
> [1] - [http://groovy-lang.org/semantics.html#Groovy-Truth]

> We need to careful for some points while we change this:
> Like:
> maxRetry = 0
> if (!maxRetry) {
>  // Not set, use a default
>  maxRetry = -1
> }
> Because groovy evaluates zero to be false, it wouldn't be possible to set
> maxRetry to zero.  So it's best not to use groovy truth for null-checks on
> numbers in some cases.
