/// tip | 豆知識

IP `0.0.0.0` は、そのマシン/サーバーで利用可能なすべての IP で待ち受けることを意味する表現として一般的に使われます。

///

ドキュメント UI では、この API の `server` が（プロキシの背後で）`/api/v1` にあることを宣言する OpenAPI スキーマも必要です。例えば:

```JSON hl_lines="4-8"
{
    "openapi": "3.1.0",

    assertThat(iia.subArray(1, 5).indexOf(1)).isEqualTo(0);
  }

  public void testIndexOf_specialValues() {
    ImmutableDoubleArray iia =
        ImmutableDoubleArray.of(-0.0, 0.0, Double.MAX_VALUE, Double.POSITIVE_INFINITY, Double.NaN);
    assertThat(iia.indexOf(-0.0)).isEqualTo(0);
    assertThat(iia.indexOf(0.0)).isEqualTo(1);
    assertThat(iia.indexOf(Double.MAX_VALUE)).isEqualTo(2);

        }

        @Test
        @DisplayName("getAttributes should return file attributes")
        void testGetAttributes() throws CIFSException {
            // Given
            int expectedAttributes = 0x20; // FILE_ATTRIBUTE_ARCHIVE
            when(mockResource.getAttributes()).thenReturn(expectedAttributes);

            // When
            int attributes = mockResource.getAttributes();

            // Then

        range = VersionRange.createFromVersionSpec("[1.0,1.1-SNAPSHOT]");
        assertTrue(range.containsVersion(new DefaultArtifactVersion("1.1-SNAPSHOT")));

        range = VersionRange.createFromVersionSpec("[5.0.9.0,5.0.10.0)");
        assertTrue(range.containsVersion(new DefaultArtifactVersion("5.0.9.0")));
    }
