## 事前定義レスポンスとカスタムの組み合わせ { #combine-predefined-responses-and-custom-ones }

多くの *path operations* に適用できる事前定義のレスポンスを用意しつつ、各 *path operation* ごとに必要なカスタムレスポンスと組み合わせたい場合があります。

そのような場合、Python の `**dict_to_unpack` による `dict` の「アンパック」テクニックを使えます:

```Python

            assertFalse(init.getContextFlag(flag));
            assertEquals(0, init.getContextFlags());
        }

        @Test
        @DisplayName("Multiple flags can be combined correctly")
        void testMultipleFlagsCombination() {
            NegTokenInit init = new NegTokenInit();

            // Set multiple flags
            init.setContextFlag(NegTokenInit.DELEGATION, true);

    @CanIgnoreReturnValue
    @Override
    public Builder<E> addAll(Iterator<? extends E> elements) {
      super.addAll(elements);
      return this;
    }

    @CanIgnoreReturnValue
    Builder<E> combine(Builder<E> builder) {
      checkNotNull(builder);
      contents.addAll(builder.contents);
      return this;
    }

    @Override
    public ImmutableList<E> build() {
      return copyOf(contents);

    ImmutableSortedSet.Builder<String> zat =
        ImmutableSortedSet.<String>naturalOrder().add("a", "b", "d", "c");
    ImmutableSortedSet<String> sortedSet = zis.combine(zat).build();
    assertThat(sortedSet).containsExactly("a", "b", "c", "d").inOrder();
  }

  // TODO(b/172823566): Use mainline testToImmutableSortedSet_customComparator once CollectorTester
  //  is usable to java7.

		}
	}

	// Defensive code: Do not allow any operation if no policy is found in the session token
	if !isOwnerDerived && len(policies) == 0 {
		return false
	}

	// 2. Combine the mapped policies into a single combined policy.

	var combinedPolicy policy.Policy
	// Policies were found, evaluate all of them.
	if !isOwnerDerived {
		availablePoliciesStr, c := sys.store.MergePolicies(strings.Join(policies, ","))

            or {@code combine.self} attributes to the children of the configuration element:</p>
            <ul>
            <li>{@code combine.children}: available values are {@code merge} (default) and {@code append},</li>
            <li>{@code combine.self}: available values are {@code merge} (default) and {@code override}.</li>

        put(entry.getKey(), entry.getValue());
      }
      return this;
    }

    @CanIgnoreReturnValue
    Builder<K, V> combine(Builder<K, V> builder) {
      entries.addAll(builder.entries);
      return this;
    }

    /**
     * Returns an {@code ImmutableRangeMap} containing the associations previously added to this
     * builder.

      this.valueComparator = checkNotNull(valueComparator, "valueComparator");
      return this;
    }

    @CanIgnoreReturnValue
    Builder<K, V> combine(Builder<K, V> other) {
      checkNotNull(other);
      entries.addAll(other.entries);
      return this;
    }

    public ImmutableMap<K, V> build() {
      return buildOrThrow();
    }

                }
            }

            assertEquals(3, validCount);
            assertTrue(offset > 0);
        }

        @Test
        @DisplayName("Should calculate combined size for multiple contexts")
        void testCombinedSizeCalculation() {
            CreateContextRequest[] contexts = new CreateContextRequest[5];
            int[] expectedSizes = { 16, 24, 32, 40, 48 };

    for (int i = end - 1; i >= start; i--) {
      if (array[i] == target) {
        return i;
      }
    }
    return -1;
  }
