Class RepositoryInitializationHandler

    public abstract class RepositoryInitializationHandler
extends Object
    A repository initialization handler is responsible for initializing a repository content.

    The handler is called each time a repository is opened in a JVM session. This can be used to create a default structure for the repository.

    To register a repository initializer MyInitHandler you should do:

    RepositoryInitializationHandler.setInstance(new MyInitHandler());

    If you want to create an initialization chain you can implement to delegate to the parent handle the default initialization and then to do your specific initialization stuff 

     
 RepositoryInitializationHandler parentHandler = RepositoryInitializationHandler.getInstance();
 MyInitHandler myHandler = new MyInitHandler(parentHandler);
 RepositoryInitializationHandler.setInstance(myHandler);
 ...
 class MyHandler extends RepositoryInitializationHandler {
      ...
      public initializeRepository(CoreSession session) {
        if (parentHandler != null) parentHandler.initializeRepository(session);
        // do my own initialization here
        ...
      }
      ...
 }

    Important Note: Use the given session to initialize the repository. Do not create other repository sessions when initializing the repository to avoid dead locks.
