public LurchTable<TKey,TValue>( LurchTableOrder ordering, int limit, int hashSize, int allocSize, int lockSize, IEqualityComparer<TKey> comparer ) | |
Parameters
- ordering
- The type of linking for the items
- limit
- The maximum allowable number of items, or int.MaxValue for unlimited
- hashSize
- The number of hash buckets to use for the collection, usually 1/2 estimated capacity
- allocSize
- The number of entries to allocate at a time, usually 1/16 estimated capacity
- lockSize
- The number of concurrency locks to preallocate, usually 1/256 estimated capacity
- comparer
- The element hash generator for keys
