cachedObjectExpiresAtMicros

public long cachedObjectExpiresAtMicros(Obj obj,
 LongSupplier clockMicros)

Description copied from interface: ObjType

Allows an object type to define how long a particular object instance can be cached.

-1L, which is the default implementation, defines that an object instance can be cached forever.

0L defines that an object instance must never be cached.

A positive value defines the timestamp in "microseconds since epoch" when the cached object can be evicted
