Timestamped Dictionary
This is a dictionary that records datetime when data is added.
Feature
- When an element is added or updated, a timestamp is recorded on the element.
- It is possible to set an upper limit on the number of elements that can be stored. (By default, it is unlimited)
- When adding elements, the oldest element is deleted if the capacity is exceeded.

Usage
Generate various types of dictionaries.
using Izayoi.Collections;
using System;
static void Main()
{
// key: int, value: long
var intKeyDicionary = new TimestampedDictionary<int, long>();
// key: Guid, value: User
var userDicionary = new TimestampedDictionary<Guid, User>();
// key: string, value: int
var stringKeyDicionary = new TimestampedDictionary<int>();
}
See timestamp.
using Izayoi.Collections;
static void Main()
{
var dictionary = new TimestampedDictionary<int, string>();
bool addResult = dictionary.TryAdd(key: 1, value: "a");
// addResult: true
bool getResult = dictionary.TryGetValue(key: 1, out var value);
// getResult: true
// value: "a"
bool getDataResult = dictionary.TryGetData(key: 1, out var data);
// getDataResult: true
// data.Timestamp: 1234567890, data.Key: 1, data.Value: "a"
var keys = dictionary.GetTimestampedKeys();
// keys[0].Timestamp: 1234567890, keys[0].Key: 1
}
Delete old data.
using Izayoi.Collections;
using System.Threading.Tasks;
static async Task Main()
{
var cache = new TimestampedDictionary<int, string>();
_ = cache.TryAdd(key: 1, value: "a");
_ = cache.TryAdd(key: 2, value: "b");
await Task.Delay(1000);
DateTimeOffset datetime = DateTimeOffset.UtcNow;
await Task.Delay(1000);
_ = cache.TryAdd(key: 3, value: "c");
await Task.Delay(1000);
// delete old data
cache.ClearBefore(datetime);
bool result1 = cache.TryGetValue(key: 1, out var value1);
// result1: false, value1: null
bool result2 = cache.TryGetValue(key: 2, out var value2);
// result2: false, value2: null
bool result3 = cache.TryGetValue(key: 3, out var value3);
// result3: true, value3: "c"
}
Enable capacity.
using Izayoi.Collections;
static void Main()
{
var dictionary = new TimestampedDictionary<int, string>(capacity: 2);
bool containsKey1;
bool addResult1 = dictionary.TryAdd(key: 1, value: "a");
// addResult1: true
bool addResult2 = dictionary.TryAdd(key: 2, value: "b");
// addResult1: true
// contains: 1, 2
containsKey1 = dictionary.ContainsKey(key: 1);
// containsKey1: true
bool addResult3 = dictionary.TryAdd(key: 3, value: "c");
// addResult3: true
// contains: 2, 3
containsKey1 = dictionary.ContainsKey(key: 1);
// containsKey1: false
bool addResult4 = dictionary.TryAdd(key: 4, value: "d");
// addResult4: true
// contains: 3, 4
bool containsKey2 = dictionary.ContainsKey(key: 2);
// containsKey2: false
}
