org.tmatesoft.hg.internal.RevisionLookup

Lite alternative to {@link HgRevisionMap}, to speed up nodeid to index conversion without consuming too much memory. E.g. for a 100k revisions, {@link HgRevisionMap} consumes 3 * (N * sizeof(int)) for indexes plus 48 bytes per Nodeid instance, total (12+48)*N = 6 mb of memory. {RevisionLookup} instead keeps only Nodeid hashes, (N * sizeof(int) = 400 kb), but is slower in lookup, O(N/2) to find potential match plus disk read operatin (or few, in an unlikely case of hash collisions). @author Artem Tikhomirov @author TMate Software Ltd.
