Example 6 with ExecutionError

use of com.google.common.util.concurrent.ExecutionError in project caffeine by ben-manes.

    Error e = new Error();
    CacheLoader<Object, Object> loader = errorLoader(e);
    LoadingCache<Object, Object> cache = CaffeinatedGuava.build(Caffeine.newBuilder().recordStats(), bulkLoader(loader));

Example 7 with ExecutionError

use of com.google.common.util.concurrent.ExecutionError in project guava by google.

the class LocalCache method load.

private V load(Object key) throws ExecutionException {
    long startTime = ticker.read();
    V calculatedValue;
    try {
        /*
       * This cast isn't safe, but we can rely on the fact that K is almost always passed to
       * Map.get(), and tools like IDEs and Findbugs can catch situations where this isn't the
       * case.
       *
       * The alternative is to add an overloaded method, but the chances of a user calling get()
       * instead of the new API and the risks inherent in adding a new API outweigh this little
       * hole.

        calculatedValue = loader.load(castKey);
