Stephen Colebourne commented on LANG-458:
-----------------------------------------
I would say that this class has a single purpose at present, and that is to act
as an guard on entry to a method, with an exception being the result. We should
not add isXxx methods returning a boolean to Validate.
Furthermore, I'm not sure there is any need for a class in [lang] that has
those boolean return types. The majority of the functions of Validate that
would be converted are available elsewhere, such as StringUtils.isEmpty, or
CollectionUtils.isEmpty.
> Add methods to return boolean from Validate.java instead of throwing
> IllegalArgumentException

> I am using Validate.java since long and find it difficult to use when I just
> want to validate collections or string.
> With current interface, I go like this:
> while(cnt < list.size()) {
> List list1 = list.get(cnt);
> try {
> Validate.notEmpty(list1);
> } catch(IllegalArgumentException e) {
> continue;
> }
> }
> much better approach is:
> while(cnt < list.size()) {
> List list1 = list.get(cnt);
> try {
> if(! Validate.notEmpty(list1)) {
> continue;
> }
> }
> If you all agree with this change, I am willing to submit a patch for this.
