Auto-compiler

Overview

Modelling is an iterative process. Often you will find yourself making many small tweaks during the building and calibrating process. Restarting your server multiple times in a short space of time can be a slow and cumbersome process. The Simudyne auto-compiler allows models to be automatically compiled when changes are made.

Set up

Enabling auto-compilation is as simple as seting a property in the simudyneSDK.properties file.

simudyneSDK.properties

nexus-server.autocompile-root=<root-to-models>

Directory structure

src/
    main/
        java/
            models/
                mortgagemodel/
                    MortgageModel.java
                tradingmodel/
                    TradingModel.java
                CreditCardModel.java    
            Main.java

If you set the autocompile root to the path src/main/java/models, the autocompiler will search each sub folder, (mortgagemodel, tradingmodel) for models. It will find the MortgageModel and the TradingModel which will both be autocompiled. The CreditCardModel, which is not in a folder will not be found.

Each sub folder inside the autocompile root path is treated as a group. Therefore, if you have multiple models in one subfolder, a change in one of them will cause all of the models in that folder to be recompiled and restarted.

                    MortgageModel.java
                    TradingModel.java
                    HelpfulClass.java
                credit/
                    CreditCardModel.java  

nexus-server.autocompile-root=src/main/java/models

If any of the three classes (MortgageModel.java, TradingModel.java or HelpfulClass.java) are changed, both MortgageModel and TradingModel will be recompiled and restared, but CreditCardModel will not be recompiled.
