Interface QuerySystem

public interface QuerySystem

... Conventions:

• QuerySystem should has public constructor with DataCollection argument This constructor is used by DataCollectioInfo to create QuerySystem.

Example:

public class SequenceQuerySystem implements QuerySystem
{
public SequenceQuerySystem(DataCollection dc)
{
...
}
...
}


All index files used by QuerySystem are registered by DataCollectionInfo.
Latter this information is used to correctly remove all data collection files.


close all indexes when QuerySystem is closed or finalised.
