[GitHub] [dubbo] TotalForgot opened issue #5111: Support passing JAVA Predicate as parameters for exposed APIs

["TotalForgot (GitHub)" <gi...@apache.org>]

Dear experts,

We are currently using Dubbo for exposing our APIs.

Many of our APIs are designed to consume JAVA Predicate as input parameters. For instance:

API side:
`boolean testSomeCondition(Predicate<String> condition);`
Implementation side:
`boolean testSomeCondition(final Predicate<String> condition) {
    final String stringFromInternal = "This string is generate only internally";
    return condition.test();
}`

Unfortunately, as far as we understand, Dubbo currently does not support the serialization of JAVA Predicate. 

**Our question is**: Does Dubbo community have any consideration in supporting JAVA Predicate in particular, JAVA lambda in general, in near future?

Best regards
TotalForgot
