Read and Write Events

.OnRead and .OnWrite are events where post-read and write actions can be added. Read and write events are needed for cache implementations where it is necessary to know which resources are used frequently or lately.

long[] accessTicks = new long[2];
IMemory<byte> memory = new BlockMemory<byte>().RWLocked();
memory.OnRead += () => accessTicks[0] = DateTime.UtcNow.Ticks;
memory.OnWrite += () => accessTicks[1] = DateTime.UtcNow.Ticks;

// Write event
memory.Add(item: 100);
// Read event
byte value = memory[0];
// Print time
Console.WriteLine(accessTicks[0]);
Console.WriteLine(accessTicks[1]);
