Sim.ts

A library heavily based on the Sim.js lib, developed by Maneesh Varshney. In fact, Sim.js was downloaded and rewritten into typescipt. It does not support all the features of the original library, because some raised errors and were not needed anyways.

License

The original library is licensed under the LGPL, so this lib is LGPL as well.

Modifications

• migrated from javascript to typescipt
• added support for realtime execution
  • you can set a timestepDuration and set realtime to true
  • every tick in the simulation lasts as long as the time set in timestepDuration
  • notice, that if you set timestepDuration = 1000 and the next event in the simulation takes place in 5 ticks, the time needed will be 5 seconds
• uses now class syntax instead of functions and prototyping
• some bug fixes occuring due to the changes to class syntax
• no subclasses of Sim anymore, every subclass is now its own class with Prefix Sim
• classes were distributed into different files for more readability
• added abstract class Entity which an entity for the sim has to extend
  • all entities have access to the same Sim and Random instance
  • also every entity has their own SimPopulation stats
• added utility class, which lets you format a number (milliseconds) to a string
• ARG_CHECK got removed entirely
• removed the processing discipline from SimFacility. It raised errors, but wasn't needed anyways so it got removed
• added a getTop method to the SimPQueue class
• added some tests
• SimPQueue checks the SimRequests priority for ordering the requests
• Simulation now suports dateTime via the luxon framework. Now you can set a dateTime and also log with this instead with simtime. The dateTime is useful if you want your Entities in the simulation behave differently, wether date or time it is
• Added support for one entity to queue Events with different priorities
