Subject [jira] [Commented] (JEXL-151) operators to manipulate j.u.Collection
Date Thu, 23 Jul 2015 15:39:04 GMT

    [ https://issues.apache.org/jira/browse/JEXL-151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14639014#comment-14639014
] 

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

> 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.
