With that, the operation IDs would be renamed from things like `items-get_items` to just `get_items`, that way the client generator can generate simpler method names.

Bununla operation ID'ler `items-get_items` gibi değerlerden sadece `get_items` olacak şekilde yeniden adlandırılır; böylece client üreteci daha basit method isimleri üretebilir.

        // Arrange
        FileEntry e = new TestFileEntry("doc.pdf", 2, 0x10, 10L, 20L, 30L, 4096L, 3);

        // Act & Assert: getters return exactly what was provided
        assertAll(() -> assertEquals("doc.pdf", e.getName()), () -> assertEquals(2, e.getType()),
                () -> assertEquals(0x10, e.getAttributes()), () -> assertEquals(10L, e.createTime()),

            throw new RuntimeException("Failed to access protected fields via reflection", e);
        }

        // Since SamrOpenAlias's constructor parameters are not directly exposed via getters in MsrpcSamrOpenAlias,
        // we cannot directly verify them here without reflection or extending SamrOpenAlias for testing.

        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

        SmbSessionImpl session = newSession();

        // Basic getters
        assertSame(configuration, session.getConfig(), "getConfig delegates to transportContext");
        assertEquals("EXAMPLE", session.getTargetDomain());

Damit würden die Operation-IDs von Dingen wie `items-get_items` in `get_items` umbenannt, sodass der Client-Generator einfachere Methodennamen generieren kann.

Після цього operation ID буде перейменовано з чогось на кшталт `items-get_items` просто на `get_items`, тож генератор клієнта зможе створити простіші назви методів.
