For each

For Each

CajuScript haves the caju.each("MY_CUSTOM_VAR_NAME", MY_ARRAY) method to do "for each", that does the interaction and load into an custom variable with the value of the current position.

Is possible know the current index and with MAPs the current KEY, using caju.index("MY_CUSTOM_VAR_NAME") for know the current index and caju.key("MY_CUSTOM_VAR_NAME") for know the current KEY from an MAP.

Array

    myArray = array.create('i', 3);
    array.set(myArray, 0, 10);
    array.set(myArray, 1, 20);
    array.set(myArray, 2, 30);
    System.out.println("---");
    caju.each("_array_item", myArray) @
        System.out.println("index: "+ caju.index("_array_item"));
        System.out.println("value: "+ _array_item);
        System.out.println("---");
    @

Collecion & Enumeration

    System.out.println("===");
    System.out.println("Collection");
    System.out.println("===");
    myCollection = java.util.ArrayList();
    myCollection.add('10');
    myCollection.add('20');
    myCollection.add('30');
    System.out.println("---");
    caju.each('_collection_item', myCollection) @
        System.out.println("index: "+ caju.index("_collection_item"));
        System.out.println("value: "+ _collection_item);
        System.out.println("---");
    @;

Map

    System.out.println("===");
    System.out.println("Map");
    System.out.println("===");
    myMap = java.util.HashMap();
    myMap.put('key1', '10');
    myMap.put('key2', '20');
    myMap.put('key3', '30');
    System.out.println("---");
    caju.each('_map_item', myMap) @
        System.out.println("index: "+ caju.index("_map_item"));
        System.out.println("key: "+ caju.key('_map_item'));
        System.out.println("value: "+ _map_item);
        System.out.println("---");
