de.hybris.platform.persistence.ManagerEJB
Direct Known Subclasses:
EnumerationManagerEJB, ExtensionEJB, ExtensionManagerEJB, LinkManagerEJB, MetaInformationManagerEJB, TypeManagerEJB
public abstract class ManagerEJB extends Object
Default abstract class for implementing a Manager. A Manager in the hybris platform is a session bean that provides methods for handling one or more types of 'Items'.
Handling means
  • Creating items
  • Removing items
  • Perfom rollback/commit on stageable items
  • Search specified items

For example a ProductManager is responsible for creating/removing and searching Products.
Additional each manager has to implement methods which are called by the system (the NotifyManager) if a item is removed or the system is initialized.

  • Method Details

    • getPersistencePool

      protected PersistencePool getPersistencePool()

    • notifyItemRemove

      public void notifyItemRemove(ItemRemote item)
      Callback method to get notified if an item in the hybris platform is going to be removed.
      Each manager can perform some cleanups.
      It is a major failure to throw an exception here to abort item removal; use canRemoveItem(ItemRemote) instead to signal your veto.

    • canRemoveItem

      public boolean canRemoveItem(ItemRemote item) throws ConsistencyCheckException
      In case a manager wants to abort the removal of an Item this method should return false. Since all manager are asked before you can assume that no changes are made when one manager aborts.
      Throws:
      ConsistencyCheckException - you can either throw an exception or return false

    • isReinitialization

      public boolean isReinitialization(Map params)

    • removeItem

      public void removeItem(ItemRemote item) throws ConsistencyCheckException
      Removes an Item which is not stageable. The following tasks are done by this method:
      1. Check if item is stageable; if it is, throw exception (we can
      2. call prepareItemRemove(ItemRemote)
      3. Depending on the given stagingMethod do:
        Productive Stage
      4. Remove staged copy (item.getStagedCopy()) of item, if it exist
      5. call NotifyManager.notifyItemRemove( item )
      6. Remove the entity
        		7.
      7. Remove staged copy (item.getStagedCopy()) of item, if it exist
      8. Mark item as removed (item.setRemoved(true)
        		9.
      Throws:
      ConsistencyCheckException

    • prepareItemRemove

      public void prepareItemRemove(ItemRemote item) throws ConsistencyCheckException
      Called before a not stageable item is removed. This is a default implementation and can be overridden by subclasses to provide consistency checks.
      Throws:
      ConsistencyCheckException
