## Dependencies for a group of *path operations* { #dependencies-for-a-group-of-path-operations }

Later, when reading about how to structure bigger applications ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md){.internal-link target=_blank}), possibly with multiple files, you will learn how to declare a single `dependencies` parameter for a group of *path operations*.

## Dependências para um grupo de *operações de rota*

Mais a frente, quando você ler sobre como estruturar aplicações maiores ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md){.internal-link target=_blank}), possivelmente com múltiplos arquivos, você aprenderá a declarar um único parâmetro `dependencies` para um grupo de *operações de rota*.

## Dependências globais

    Interner<Integer> pool = Interners.newWeakInterner();
    assertSame(canonical, pool.intern(canonical));

    WeakReference<Integer> signal = new WeakReference<>(canonical);
    canonical = null; // Hint to the JIT that canonical is unreachable

    GcFinalization.awaitClear(signal);
    assertSame(not, pool.intern(not));
  }

  public void testAsFunction_simplistic() {
    String canonical = "a";

            assertEquals(status, echoResponse.getErrorCode());
        }
    }

    @Nested
    @DisplayName("Signed Flag Tests")
    class SignedFlagTests {

        @Test
        @DisplayName("Should detect signed flag")
        void testIsSigned() {
            assertFalse(echoResponse.isSigned());

            echoResponse.addFlags(ServerMessageBlock2.SMB2_FLAGS_SIGNED);

  }

  @Override
  public @Nullable E higher(@ParametricNullness E e) {
    return delegate().higher(e);
  }

  /**

        @DisplayName("Should handle signed/unsigned integer boundaries")
        void shouldHandleSignedUnsignedBoundaries() {
            // Test that GENERIC_READ is the highest bit (0x80000000)
            assertEquals(0x80000000, ACE.GENERIC_READ, "GENERIC_READ should be 0x80000000");
