Class LookupTable

java.lang.Object
  ai.LookupTable

public class LookupTable
extends Object

The LookupTable represents an efficient hash table to Variations with two properties that make a regular HashMap unsuitable: - The LookupTable uses bounded memory, choosing to replace old cells rather than expand. - The LookupTable does not check for collisions in hashCode. As a result, LookupTable is fast, space-efficient, and occasionally wrong. LookupTable is thread-safe.
