Method Detail

columnView

public <T> ColumnView<T> columnView(Attribute<T> attribute)

TODO PERFORMANCE Cache list views in Order to minimize number of objects.

TODO Return an unmodifiable view of the column.

Specified by:

columnView in interface Table

Overrides:

columnView in class DatabaseI

Type Parameters:

T -

Parameters:

attribute -

Returns:

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:

add in interface Database

Overrides:

add in class DatabaseI

Parameters:

line -

Returns:

addTranslated

protected Line addTranslated(net.splitcells.dem.data.set.list.List<Object> lineValues,
                             int index)

Overrides:

addTranslated in class DatabaseI

Parameters:

lineValues - TODO Support Domable.toDom() for logging.

addTranslated

public Line addTranslated(net.splitcells.dem.data.set.list.List<? extends Object> lineValues)

TODO REMOVE Code duplication of addTranslated(net.splitcells.dem.data.set.list.List<java.lang.Object>, int) methods.

Specified by:

addTranslated in interface Database

Overrides:

addTranslated in class DatabaseI

public void remove(int lineIndex)

Specified by:

remove in interface Database

Overrides:

remove in class DatabaseI
