Claus Ibsen commented on CAMEL-15922:
-------------------------------------
Lets wait for dropping Java 8 as source generating as Java 11 codes make this
easier
> camel-core - Compiled simple support nested functions
> -----------------------------------------------------
>
> Key: CAMEL-15922
> URL: https://issues.apache.org/jira/browse/CAMEL-15922
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 3.7.0
> Reporter: Claus Ibsen
> Priority: Major
> Fix For: 3.x
>
>
> The csimple language does not support the following feature in its first
> release
> - nested functions (${xxx} inside existing ${xxx} functions))
> - the null safe operator (?)
> We need a smarter source code generator for this to support this, that
> supports building up multiple statements and assign to local variables, and
> branches for the null safe operator, and also to understand types of method
> calls for nested functions so its of the same type from the java compiler
> point of view.
