Examples of it.unimi.dsi.mg4j.index.cluster.IdentityDocumentalStrategy

it.unimi.dsi.mg4j.index.cluster.IdentityDocumentalStrategy
A documental strategy that maps identically local to global pointers and viceversa.
When clustering a posteriory a set of previously built renumbered indices using a {@link it.unimi.dsi.mg4j.index.cluster.DocumentalMergedCluster}, local document pointers are actually global document pointers. In this case, an instance of this class should be used as a strategy for the cluster. @author Sebastiano Vigna
