```
public abstract class ManagerEJB
extends java.lang.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 Detail

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(java.util.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:

Check if item is stageable; if it is, throw exception (we can
call prepareItemRemove(ItemRemote)

Depending on the given stagingMethod do:

Productive	Stage
Remove staged copy (item.getStagedCopy()) of item, if it exist call NotifyManager.notifyItemRemove( item ) Remove the entity	Remove staged copy (item.getStagedCopy()) of item, if it exist Mark item as removed (item.setRemoved(true)

Throws:: ConsistencyCheckException
See Also:: prepareItemRemove(ItemRemote)

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

removeItem(ItemRemote)

ejbCreate
```
public void ejbCreate()
```
Default implementation of EJB method.
Each manager have to provide a non parameter create-method. This implementation just returns and does nothing.

ejbPostCreate
```
public void ejbPostCreate()
```
Default implementation of EJB method.
Each manager have to provide a non parameter postCreate-method. This implementation just returns and does nothing.
