Interface ExceptionPropagator<K>

public interface ExceptionPropagator<K>

In read through mode exceptions are cached. Every time an entry is requested from the cache a new exception is generated that wraps the original loader exception in a CacheLoaderException. This behavior can be modified by registering a custom exception propagator.

Exceptions should not be thrown directly but wrapped. Using this customization it is possible to change the exceptions type or the message according to the information available.
