public SupplierDataContainer(long timeToLive)
The old value is not removed from memory until the supplier is called again.
timeToLive - TTL that determines how long a CachingSupplier value is deemed valid.public <T> void putRawData(Key<T> key, T obj)

DataContainerIf the supplier is called the value is cached according to the implementation of the container. What the container does with the supplier depends on the implementation.
