28.4.6 Exporting Scheme variables

As for the C connection, a Scheme variable (or function) can be exported to the Java world if and only if it is also exported using an export Java clause. Type information is given in the Scheme exportation, thus, the only requirement for a variable to be Java exported is to be given a Java name. The Java <export-clause> does this:

<export-clause> → (export <ident> <string>)

Here is an example of exportation:

(module example
   (export (fib::long ::long))
   (java (export fib "scheme_fib")))

(define (fib x) (if (< x 2) 1 ...))
