Class VLPaCoTrieDistributor<T>

  • All Implemented Interfaces:
    it.unimi.dsi.fastutil.Function<T,​java.lang.Long>, it.unimi.dsi.fastutil.objects.Object2LongFunction<T>, it.unimi.dsi.fastutil.Size64, java.io.Serializable, java.util.function.Function<T,​java.lang.Long>, java.util.function.ToLongFunction<T>
    public class VLPaCoTrieDistributor<T>
extends it.unimi.dsi.fastutil.objects.AbstractObject2LongFunction<T>
implements it.unimi.dsi.fastutil.Size64
    A version of a PaCoTrieDistributor whose space usage depends on the average string length, rather than on the maximum string length; mainly of theoretical interest.

        Creates a partial compacted trie using given elements, bucket size and transformation strategy.
        Parameters:
        elements - the elements among which the trie must be able to rank.
        bucketSize - the size of a bucket.
        transformationStrategy - a transformation strategy that must turn the elements in elements into a list of distinct, lexicographically increasing (in iteration order) bit vectors.
        Throws:
        java.io.IOException
