List

A list represents a list of other variables

Constructor

To create a list, you can use a constructor or use square brackets to enclose a list of variables.

// Create an empty list
l1 = List()

// Also construct an empty list
l1 = []

// Create a list of variables
l2 = ["Hello", 1, l1]

info

Notice how you can also add a list as an element of a list, in fact you can add any other variable as an element of a list.

Properties

A list has the following properties:

Name	Description	Type
size	Returns the number of elements in the list	Scalar(Integer)
description	The description of this list	String
name	The name of this list	String

Methods

A list has the following methods:

Name	Description	Return Type
add(element)	Add a variable to the list of elements	The current list
add(position, element)	Adds a variable to the list in the supplied position (0 being first)	The current list
addAll(list)	Adds all the elements from the supplied list into this list	The current list
subList(start, end)	Gets a sublist from the elements in the list from the start to the end	New List
remove(index)	Removes an element from the list at the specified position (0 being first)	Void
remove(item)	Removes an element from the list	Void
set(index, element)	Replaces the element at the specified position in this list with the specified element	Void

Using Lists

You can directly access an element in a list using the square brackets and an index starting at 0, e.g. the following code would print out World

// Create a list of variables
l3 = ["Hello", "World"]
print l3[1]

You can also replace elements in the list using the same technique, e.g.

// Replace World with ODSL
l3[1] = "ODSL"
print l3[1]

You can also iterate through the elements of the list using a for loop, e.g.

// Iterate through the list
for element in l3
    print element
next
