Groovy findIndexValues return List<Long>
collections, groovy, types
Solution
That's how that method works. It traverses the collection with an iterator and keeps track of the matching indexes as longs. In theory, it supports collections larger than `Integer.MAX_VALUE`, although I'm doubtful this is useful in practice.
You can work around it with:
indices.each { println foo[it as int] }
Problem
I must be going crazy but why is Groovy findIndexValues returning `List<long>`? Can I get the indices in Integer? ``` foo = ['a','b','d','e', 'e','e'] indices = foo.findIndexValues { it == 'e'} indices.each { println foo[it] } ``` The above will crash because foo collection cannot handle a long as a accessing index. Am I not using the language as it should be?
