![]() With them you can have a fixed set of options for a variable / database entry / parameter and do have to worry less about parsing, redundancy and spelling mistakes. Option Lists make your life easier in AnyLogic. For the latter you can manually enter the Enum name in the field and still use it, for the database you cannot use it at all. However, there is a restriction compared to the AnyLogic Option List: You will not be able to use this enums for the internal database, and they won't show up in the dropdown for the type defintion of variables. The enum you defined in this way in Java code can be referenced in the agents where you defined it and all agents that are inside it. You avoid redundancies and spelling errors by limiting the number of possible entries.Why store such information in an enum and not in a simple String? There are a handful of benefits: ), the job levels in your company (Dishwasher, Cook, Boss). For example the four directions (North, East, South, West), the seven weekdays (Monday, Tuesday. Why and when should I use it?Īs the Java documentation puts it: You should use enum types any time you need to represent a fixed set of constants. That's it, now the Option List is ready to be used. By Java convention, the name should start with a capital letter ( Weekday), and the entries are in all caps ( MONDAY). In the AnyLogic Project tab, right click on any entry of your project, then select:Ī window for defining the name of the option list, as well as the entries appears. Also the Option Lists defined in AnyLogic can be shown and edited in the project structure tree. The advantage of the AnyLogic version: it offers a nice little GUI to define enums without the need for Java code. That is because it is actually (almost) congruent to the AnyLogic Option List, which uses Java Enums in the background! If you are familiar with Java, you might be wondering that this sounds like Java Enums. Sort of like a dropdown, that only allows you to set certain values. Option List is a data type that restricts the possible values of a variable to a number of predefined choices. In this article I will explain the use and benefits of this feature. I didn't use them for quite some time, but since I started, I deploy them in almost any model. Comparison operations – Notation: >= View more.There is a lesser known feature in AnyLogic that will allow you to build more structured models: Option Lists. ![]() 3/2=1, and 2/3=0 Multiplication operators have priority over addition operators The "+" operator allows operands of type String Notation: + – * / % (remainder) In integer divisions, the fraction part is lost, e.g. ArrayList LinkedList: Represents collections of objects HyperArray: Represents multi-dimensional array …many others. Primitive Types – double: Represents real numbers: 1.43, 3.6E18, -14.0 – int: Represents integer numbers: 12, 16384, -5000 – boolean: Represents Boolean (true/false) values.Java is case-sensitive: MyVar is different to myVar! Spaces are not allowed in names: "My Var" is an illegal name! Each statement has to be finished with " ": MyVar=150 Each function has to have parenthesis: time(), add(a) Mind integer division: 3/2=1, not 1.5 Boolean values are only true and false, you cannot use 1 and 0 Dot "." brings you "inside" the object: () Array elements have indexes from 0 to n-1 G54SIM You need to understand Java data types, expression, and statement syntax.General remarks – You do not have to learn full OO programming.Since AnyLogic 7 … – Everything is called "Agent" (entities, resources, agents, …) – PLE version limits number of entities per simulation run to 50,000.We use AnyLogic 7.2.0 PLE – You will have to apply for a new license key whenever you change your desktop machine (not sure about the virtual desktop)į1: Help Ctrl-Space: Code completion support Ctrl-Enter: Perform refactoring (replace name occurrences) Make sure you select the correct model when pressing "Run" Make sure you set up model time units correctly in the "Model" Use the "magic lightbulb".G54SIM (Spring 2016) Lab 02 Introduction to AnyLogic
