Henri Biestro commented on JEXL-151:
------------------------------------
startsWith, endsWith and contains/matches are now overloadable operators (like
empty(...)).
Default contains/matches now uses containsAll when both arguments are
collections.
> operators to manipulate j.u.Collection

> Priority: Minor
> Fix For: Later
>
>
> New operators to add or remove collection items to/from Collection. Operators
> can be named as += and -= respectively, or any other way. Operator += can be
> mapped to Collection.addAll(Collection c) if right argument is Collection or
> to Collection.add(Object o) otherwise. Operator -= can be mapped to
> Collection.removeAll(Collection c) if right argument is Collection or to
> Collection.remove(Object o) otherwise. Extend operators =~ (!~) to support
> CollectionA =~ CollectionB usage, in which case it should map to
> B.containsAll(A) operation.
