# Extendendo o OpenAPI

Existem alguns casos em que pode ser necessário modificar o esquema OpenAPI gerado.

Nesta seção, você verá como fazer isso.

## O processo normal

O processo normal (padrão) é o seguinte:

Uma aplicação (instância) do `FastAPI` possui um método `.openapi()` que deve retornar o esquema OpenAPI.

    /**
     * Gets the creation time.
     *
     * @return the creation time in milliseconds since epoch
     */
    long createTime();

    /**
     * Gets the last modified time.
     *
     * @return the last modified time in milliseconds since epoch
     */
    long lastModified();

    /**
     * Gets the file size.
     *
     * @return the file size in bytes
     */
    long length();

            // When
            var field = Handler.class.getField("DEFAULT_HTTPS_PORT");

            // Then
            assertTrue(Modifier.isPublic(field.getModifiers()));
            assertTrue(Modifier.isStatic(field.getModifiers()));
            assertTrue(Modifier.isFinal(field.getModifiers()));
            assertEquals(int.class, field.getType());
        }
    }

    public void test_isPublicClass() {
        assertTrue("FessWebResourceRoot should be public", java.lang.reflect.Modifier.isPublic(FessWebResourceRoot.class.getModifiers()));
        assertFalse("FessWebResourceRoot should not be abstract",
                java.lang.reflect.Modifier.isAbstract(FessWebResourceRoot.class.getModifiers()));
    }

     *
     * @return the not modified HTTP codes
     */
    public int[] getNotModifiedHttpCodes() {
        return notModifiedHttpCodes;
    }

    /**
     * Sets the not modified HTTP codes.
     * @param notModifiedHttpCodes The not modified HTTP codes to set.
     */

// The returned object may not be modified.
func (sys *BucketMetadataSys) GetNotificationConfig(bucket string) (*event.Config, error) {
	meta, _, err := sys.GetConfig(GlobalContext, bucket)
	if err != nil {
		return nil, err
	}
	return meta.notificationConfig, nil
}

// GetSSEConfig returns configured SSE config
// The returned object may not be modified.

	// always emitted. The legacy MS-DOS date field is encoded according to the
	// location of the Modified time.
	Modified time.Time

	// ModifiedTime is an MS-DOS-encoded time.
	//
	// Deprecated: Use Modified instead.
	ModifiedTime uint16

	// ModifiedDate is an MS-DOS-encoded date.
	//
	// Deprecated: Use Modified instead.
	ModifiedDate uint16

	// CRC32 is the CRC32 checksum of the file content.

            Method setObjectMethod = WebApiUtil.class.getMethod("setObject", String.class, Object.class);
            assertTrue("setObject should be static", java.lang.reflect.Modifier.isStatic(setObjectMethod.getModifiers()));
            assertTrue("setObject should be public", java.lang.reflect.Modifier.isPublic(setObjectMethod.getModifiers()));
            assertEquals("setObject should return void", void.class, setObjectMethod.getReturnType());
