## Simple and Powerful { #simple-and-powerful }

Although the hierarchical dependency injection system is very simple to define and use, it's still very powerful.

You can define dependencies that in turn can define dependencies themselves.

        return args;
    }

    @Override
    public String getMessage() {
        return message;
    }

    /**
     * Returns a simple message without a message code.
     *
     * @return simple message without message code
     */
    public final String getSimpleMessage() {
        return simpleMessage;
    }

        assertSame(name1, name2); // Should be same instance
    }

    /**
     * Test searcher with simple class name.
     */
    @Test
    public void test_simpleClassNameSearcher() {
        final SimpleSearcher searcher = new SimpleSearcher();
        assertEquals("simple", searcher.getName());
    }

    /**
     * Test searcher extending another searcher.
     */
    @Test

# Build execution model

At the highest level, Gradle's execution model is quite simple:

Below is the protocol in some more detail:

1. The client looks for a compatible idle daemon. If there isn't one, it starts a new daemon.
2. The client connects to the idle daemon and sends it a request to do some work. If the daemon is no longer running, the client starts again.

*.pbxproj
*.xcworkspace

/tensorflow/lite/**/ios/BUILD
/tensorflow/lite/**/objc/BUILD
/tensorflow/lite/**/swift/BUILD
/tensorflow/lite/examples/ios/simple/data/*.tflite
/tensorflow/lite/examples/ios/simple/data/*.txt

Apart from all the fancy words used here, the **Dependency Injection** system is quite simple.

Just functions that look the same as the *path operation functions*.

But still, it is very powerful, and allows you to declare arbitrarily deeply nested dependency "graphs" (trees).

/// tip

All this might not seem as useful with these simple examples.

But you will see how useful it is in the chapters about **security**.

    } catch (IOException | ClassNotFoundException e) {
      throw new AssertionError(e);
    }
  }

  public SampleElements<E> samples() {

    return delegate.createArray(length);

  @Override
