Package net.splitcells.gel.data.database

Class DatabaseMetaAspect

java.lang.Object

net.splitcells.gel.data.database.DatabaseMetaAspect

All Implemented Interfaces:

net.splitcells.dem.data.Identifiable, net.splitcells.dem.lang.dom.Domable, net.splitcells.dem.object.Discoverable, Database, Table

public class DatabaseMetaAspect
extends Object
implements Database

This aspect adds mainly logging and runtime check functionality to Database instances.

TODO Make this an aspect in order to make it usable for other implementations of Database.

TODO Require the usage of a non empty name during construction.

TODO Invalidate Lines pointing to an index where values are already replaced.

TODO PERFORMANCE Abstract Database implementation with generic storage in order to simplify implementation and maintenance row and column based Databases.

TODO IDEA Implement Java collection interface.

Method Detail

databaseIRef

public static Database databaseIRef(Database database)

add

public Line add(Line line)

TODO PERFORMANCE No copies have to be created, as it is guaranteed that a Line does not change its content during its life cycle. This is important for constraints.

TODO Test whether the line is added to the correct place.

TODO FIX Why does List not work?

TODO PERFORMANCE Reduce the high number of copies.

Specified by:
