ManageableVector

public ManageableVector()

Method Detail

ojbAdd

public void ojbAdd(java.lang.Object anObject)

add a single Object to the Collection. This method is used during reading Collection elements from the database. Thus it is is save to cast anObject 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)

adds a Collection to this collection. Used in reading Extents from the Database. Thus it is save to cast otherCollection to this.getClass().

Specified by:

ojbAddAll in interface ManageableCollection

Parameters:

otherCollection - The added collection

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

ojbIterator

public java.util.Iterator ojbIterator()

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
