Class HashLongLongArray

  • public class HashLongLongArray
extends java.lang.Object
    A Hash using primitive types instead or warped object The idea is to be able to add many long values for each key This could be implemented by simply doing HashMap > (but it would consume much more memory) Note: We call each 'long[]' a bucket WARNING: This collection does NOT allow elements to be deleted! But you can replace values.
