Class Jodd

java.lang.Object

jodd.Jodd

public class Jodd
extends java.lang.Object

Jodd! This is the simple module manager for Jodd modules. On the very first access, all modules get loaded and information about available modules is set. In some environments such OSGI, however, classloader lookup does not work. Then you need to manually initialize all Jodd components that are in use.

Each module must have the following code blocK at the bottom of the class:

 static {
     Jodd.initModule();
 }
 public static void init() {}
 

How Jodd module gets loaded and initialized?

There are two stages Jodd's modules are going through: 1) loading and 2) initialization. Loading is basically detecting if the module exist. Initialization runs some additional optional code block.

There are two ways how modules are loaded:

By explicitly calling initAllModules() - or by simply accessing the Jodd class (see JODD :). This method loads all Jodd modules by simply loading each class. When class is loaded, it's static block is executed, and therefore the init() method as well:

 Jodd.static -> Jodd.initAllModules() -> JoddModule.NAME.static -> JoddModule.NAME.init() -> Jodd.initModule
 

Second way is just by using the module's static class. It will load Jodd class as well:

 JoddModule.static -> Jodd.static -> Jodd.initAllModules() -> ...
 

Initialization happens once when all modules are loaded. It consist of running the initialization code blocks.

isModuleLoaded

public static boolean isModuleLoaded(Jodd.JoddModule module)

Returns true if module is loaded.

initModule

public static void initModule()

initModule(Runnable)

initModule

public static void initModule(java.lang.Runnable initRunnable)

Initializes the Jodd module. Must be called only from the module's class, since it resolves the module from the calling hierarchy.
