Henri Yandell commented on LANG-848:
------------------------------------
My main thought is that the JVM should auto-convert an Iterable to an Object[]
for varargs :)
Failing that, I think we should have an ArrayUtils.iteratorToArray() method.
public static E[] iteratorToArray(Iterator<E> iterator);
That would allow for StringUtils.isAnyBlank(
ArrayUtils.iteratorToArray(somecharacterList.iterator()) );
I'm not sure if I'm playing too fast and loose with the generics there without
trying it :) I think we need the varargs versions of methods, but I'm not
convinced by the need for Iterable. It increases the code and typically our
code isn't stream based - ie: people in restricted memory situations can create
custom versions of the function they want.
> Improve StringUtils.is(Not)Blank with a CharSequence... version

> Key: LANG-848
> URL: https://issues.apache.org/jira/browse/LANG-848
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Affects Versions: 3.1
> Reporter: Alexander Muthmann
> Fix For: 3.2
>
>
> Currently it's only possible to compare a single CharSequence per
> is(Not)Blank/is(Not)Empty call.
> This should be changed to support multiple CharSequences in a single call.
> {code}
> if(StringUtils.isNotBlank(foo) && StringUtils.isNotBlank(bar) && ...)
> {code}
> could be changed to
> {code}
> if(StringUtils.isNotBlank(foo, bar, ...)
> {code}
> As there are two possible ways to combine the results (AND and OR), it'd be
> necessary to create multiple methods.
> {code}
> isAnyBlank(CharSequence... cs)
> isNoneBlank(CharSequence... cs)
> isAnyEmpty(CharSequence... cs)
> isNoneEmpty(CharSequence... cs)
> {code}
> I could implement those methods and contribute them via github if there is
> any interest from project's side.
