Henri Biestro updated JEXL-268: ------------------------------- Fix Version/s: Later > Jexl lambdas as parameters to new Java8 methods > ----------------------------------------------- > > Key: JEXL-268 > URL: https://issues.apache.org/jira/browse/JEXL-268 > Project: Commons JEXL > Issue Type: New Feature > Affects Versions: 3.1 > Reporter: Dmitri Blinov > Priority: Minor > Fix For: Later > > > Java8 introduced functional interfaces, among them {{Function}} and > {{BiFunction}} interfaces which are used as parameters to method calls, for > example, {{Map.computeIfAbsent()}} or {{Map.computeIfPresent()}}. In Jexl we > have lambdas which in theory are good candidates to construct a {{Function}} > for lambda with one parameter, and a {{BiFunction}} for lambda with two > parameters. > The problem is Jexl can not currently support Java8 features and all > instances of lambda are of single {{internal.Closure}} class, which should > not try to implement both interfaces at once. One of the solutions, IMO, is > to have a feature to overload lamda creations to construct custom lambda > classes without shaking Jexl code tree. -- This message was sent by Atlassian Jira (v8.3.4#803005)
