Constructor Detail

ManageableHashMap

public ManageableHashMap()
Method Detail

ojbAdd

public void ojbAdd(java.lang.Object anObject)
Description copied from interface: ManageableCollection
Adds a single object to the Collection. This method is used during reading collection elements from the database. Thus it is safe to cast the object to the underlying element type of the collection.

Specified by:
ojbAdd in interface ManageableCollection
Parameters:
anObject - The object to add

ojbAddAll

public void ojbAddAll(ManageableCollection otherCollection)
Description copied from interface: ManageableCollection
Adds another collection to this collection. Used in reading extents from the database. Thus it is safe to cast the given collection to this class.

Specified by:
ojbAddAll in interface ManageableCollection
Parameters:
otherCollection - The added collection

ojbIterator

public java.util.Iterator ojbIterator()
Description copied from interface: ManageableCollection
Returns an iterator over all elements in the collection. Used during store and delete operations. If the implementor does not return an iterator over ALL elements, OJB cannot store and delete all elements properly.

Specified by:
ojbIterator in interface ManageableCollection
Returns:
The iterator

afterStore

public void afterStore(PersistenceBroker broker)
                throws PersistenceBrokerException
Description copied from interface: ManageableCollection
A callback method to implement 'removal-aware' (track removed objects and delete them by its own) collection implementations.

Specified by:
afterStore in interface ManageableCollection
Parameters:
broker - The persistence broker
Throws:
PersistenceBrokerException
