#### `lru_cache` Technical Details

`@lru_cache` modifies the function it decorates to return the same value that was returned the first time, instead of computing it again, executing the code of the function every time.

              case 1:
                return 1;
              case 2:
                return endOfData();
              default:
                throw new AssertionError("Should not have been invoked again");
            }
          }
        };

    assertTrue(iter.hasNext());
    assertEquals(0, (int) iter.next());

    // verify idempotence of hasNext()
    assertTrue(iter.hasNext());

		}
		tracker.setObject("")
		tracker.setBucket(bucket)
		// Heal current bucket again in case if it is failed
		// in the beginning of erasure set healing
		if err := bgSeq.healBucket(objAPI, bucket, true); err != nil {
			// Set this such that when we return this function
			// we let the caller retry this disk again for the
			// buckets that failed healing.
			retErr = err
			healingLogIf(ctx, err)
			continue

    future. (Previously, we sometimes removed such APIs after a deprecation
    period. The last release to remove non-`@Beta` APIs was Guava 21.0.) Even
    `@Deprecated` APIs will remain (again, unless they are `@Beta`). We have no
    plans to start removing things again, but officially, we're leaving our
    options open in case of surprises (like, say, a serious security problem).

3.  Guava has one dependency that is needed for linkage at runtime:

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

#### A "professional" attack

      for (Future<?> future : localFutures) {
        future.cancel(wasInterrupted);
      }
    }
    /*
     * We don't call clearSeenExceptions() until processCompleted(). Prior to that, it may be needed
     * again if some outstanding input fails.
     */
  }

  @Override
  @CheckForNull
  protected final String pendingToString() {
    @RetainedLocalRef ImmutableCollection<? extends Future<?>> localFutures = futures;

This is very useful when you need to:

* Have shared logic (the same code logic again and again).
* Share database connections.
* Enforce security, authentication, role requirements, etc.
* And many other things...

All these, while minimizing code repetition.

## First Steps

    Using the cache in this step will **save** you a lot of **time** when building the image again and again during development, instead of **downloading and installing** all the dependencies **every time**.

5. Copy the `./app` directory inside the `/code` directory.
