org.cache2k.core.ExceptionWrapper<K>

All Implemented Interfaces:

org.cache2k.integration.ExceptionInformation

public class ExceptionWrapper<K>
extends Object
implements org.cache2k.integration.ExceptionInformation

We use instances of the exception wrapper for the value field in the entry. This way we can store exceptions without needing additional memory, if no exceptions happen.
