28.4.5 Declaring Java arrays

Java arrays may be allocated and used inside Scheme code. The syntax of a Java array module clause is:

<array-clause> → (array <ident> <typed-ident>)

The <typed-ident> must refer to the name of an existing type (i.e., a primitive Bigloo type, a Bigloo class, an already defined Java class or an already defined Java array). For an array named ar, Bigloo generates:

• a creator named make-ar which is a function of one integer argument.
• a predicate named ar?.
• a getter named ar-ref which is a function of one integer argument.
• a setter named ar-set! which is a function of two arguments, an integer and a value of the array item types.
• a length named ar-length.

Example:

(module foo
   (java (array int* ::int)
         (class bar
            (method static hello::int (::int*) "hello")
            "bar"))
   (main main))

(define (main argv)
   (let ((tab (make-int* 2)))
      (int*-set! tab 0 3)
      (int*-set! tab 1 6)
      (print (bar-hello tab))))
