Add an onTimeUpdate Event

[Gagafeee]

I was thinking, how can i execute a function each time the expiration Time decrease like

ExpiringMap<K, V> Timer = ExpiringMap.builder()
.expiration(10, TimeUnit.SECONDS)
.onTimeUpdate( setTime() )
.build();

Where setTime() is called each second until the value expire.

function called depending on TimeUnit value
called each milisecond if the expiration time is writed in milisecond
