Arrays and maps

Here is the code used in this lesson:

//ARRAYS

RuleContext arrays {
    Rule rule {
        // Array array
        
        Array arString = [“hello”, “bye”, “other”]
        Array arLocation = [Location(), Location()]
        Array arBool = [true, false, true, false]
        
        Integer a = arString.size() // 3
        
        String b = arString.get(2) // "other"
        
        arString.remove(1) // ["hello", "other"]
        
        String c = arString.pop() // ["hello"] // c == "other"
        
        Array arInt = arString.selected() // [] // it has no elements selected
        
        arString.setSelected([0]) // when selected() is executed again, it will return [0]
        
        Location loc = arLocation.shift() // [Location()] // it returns the removed element
        
        arBool.reverse() // [false, true, false, true]
        
        Array arInteger = [5, -1, 0, 9, 2]
        
        arInteger.sort() // [-1, 0, 2, 5, 9]
        
        arString.removeAll() // []
        
        Array arInteger1 = arInteger.clone() 
        
        Bool c = (arInteger1 == arInteger) // false
        
        Integer int = arInteger.indexOf(9) // 4
        int = arInteger.indexOf(4) // -1
        
        arString.add(“other”) // [“other”]
        
        arInteger.set(3, -4) // [-1, 0, 2, -4, 5, 9]
        
        arInteger.push(-1) // [-1, 0, 2, -4, 5, 9, -1]
        
        Array arInteger9 = [1, 2, -3]
        
        arInteger9.concat(arInteger) // [1, 2, -3, -1, 0, 2, -4, 5, 9, -1]
    }
}

//MAPS

RuleContext maps {
    Rule rule{
        // Map map
        
        Map mapString = {"a": "hello", "b": "bye", "c": "other"}
        Map mapInteger = {"a": 1, "b": 2, "c": 3}
        
        Integer a = mapString.size() // 3
        
        String b = mapString.get("b") // "bye"
        
        String c = mapString.get("c", "defaultValue") // "other"
        c = mapString.get("d", "defaultValue") // "defaultValue"
        
        mapString.remove("a") // {"b": "bye", "c": "other"}
        
        mapString.removeAll() // {}
        
        Map mapInteger1 = mapInteger.clone()
        Bool d = mapInteger1 == mapInteger // false, different references
        
        mapInteger.hasKey("a") // true
        mapInteger.hasKey("other") // false
        
        Array keys = mapInteger.keys() // ["a", "b", "c"]
        
        Array values = mapInteger.values() // [1, 2, 3]
        
        mapInteger.set("key1", 5) // {"a": 1, "b": 2, "c": 3, "key1": 5}
    }
}
