Class IListMetadata

java.lang.Object

org.egothor.store.IListMetadata

All Implemented Interfaces:

IListMetadata

Direct Known Subclasses:

IListMetadataRead, IListMetadataWrite

public class IListMetadata
extends Object
implements IListMetadata

The IListMetadata class defines the core metadata of the inverted list, its length. The length of the list will be needed for many calculations, for example, calculation of inverted document frequency. Other properties are not important for core operations so they are implemented in sub-classes.
