  ru.biosoft.access.DataElementSupport
      ru.biosoft.access.AbstractDataCollection
          ru.biosoft.access.DerivedDataCollection

All Implemented Interfaces:

DataCollection, DataElement

Direct Known Subclasses:

FilteredDataCollection, Module, TransformedDataCollection, VariablesDataCollection

public class DerivedDataCollection

extends AbstractDataCollection

General class for derived data collection.

Subclasses should provide the difference of derived data collection from primary one.

Derived data collection is listener of primary data collection. This implementation provides delegation primary data collection events to listeners of derived data collection.

Pendung:

high we do not close primry collection. It is subclasses responcibility.
