----------------------------------
Summary: operators to manipulate j.u.Collection
Key: JEXL-151
URL: https://issues.apache.org/jira/browse/JEXL-151
Project: Commons JEXL
Issue Type: New Feature
Affects Versions: 3.0
Reporter: Dmitri Blinov
Priority: Minor
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.
