public class CacheException

extends java.lang.Exception

CacheException is a generic exception, which indicates a cache error has occurred. All the other cache exceptions are the subclass of this class. All the methods in the cache package only throw CacheException or the sub class of it. CacheException may have a base exception, which is the exception that originally occurred. User can catch a CacheException, and then further examine the base exception to find the reason exception happens.

For example, this can be a sample usage model:

      try
      {
        Object obj = cacheAccess.get("foo");
        // ... lots of lines here ...
      }
      catch (CacheException ex)
      {
        ex.printStackTrace();
        Exception base = ex.getBaseException();
        if (base != null)
          base.printStackTrace();
      }
      catch (Exception ex)
      {
         // handle other exceptions
      }
