Subject [jira] [Commented] (GROOVY-7432) Enhance CharSequence with appropriate Iterable extension methods
Date Tue, 09 Jun 2015 16:01:00 GMT


Peter Ledbrook commented on GROOVY-7432:

These are just a few notes I want to add to the pull request to bring reviewers' attention
to anything I'm uncertain about.

* Will the return type signature on {{groupBy()}} work in a type-checked environment?
* {{containsAll()}} accepts a {{CharSequence[]}}, which means that objects of type {{String[]}}
need to be converted, otherwise you get a {{MethodMissingException}}. Does that seem reasonable?
* Should return types, particularly in generics, use {{String}} instead of {{CharSequence}}
since strings are invariably returned from those methods?

> Groovy enables developers to treat {{CharSequence}}s as if they were true sequences.
For example, you can use a for loop and the array index operator. 
> Some extension methods are missing though. One I was hoping to find was the {{count(Closure)}}
method. I think it makes sense to incorporate any {{Iterable}} extension methods into {{CharSequence}}
as well.
