Class FlatHashList

  • All Implemented Interfaces:
    FlatHashIterable, ListOfHash
    public final class FlatHashList
extends java.lang.Object
implements ListOfHash
    This class is used when the number of Hash returned y a function is not necessarily known in advance but has an upper bound. It is basically a read-only array list on long primitives.

      • FlatHashList

        public FlatHashList​(int depth,
                    int capacity)
