Uwagi

Ten konstruktor tworzy CipherReference obiekt przy użyciu identyfikatora URI (Uniform Resource Identifier), który wskazuje zaszyfrowane dane. Następnie obiekt służy do przekazywania informacji referencyjnych dla CipherData obiektu.

Identyfikator URI umożliwia wyznaczenie pliku XML zawierającego zaszyfrowane dane. Na przykład:

String uri = "http://www.woodgrovebank.com/document.xml";

Można również użyć częściowego identyfikatora URI, aby wyznaczyć, że tylko część dokumentu XML ma być zaszyfrowana. Załóżmy na przykład, że dokument XML o nazwie document.xml zawiera dwa MyForm elementy, jak pokazano w poniższym przykładzie kodu XML:

<MyForm Id='Form1'>

<! -- Form data here -->

</MyForm>

<MyForm Id='Form2'>

<! -- Form data here -->

</MyForm>

Zawartość można zaszyfrować tylko przy Form2 użyciu identyfikatora URI, takiego jak:

String uri = "http://www.woodgrovebank.com/document.xml#Form2";

Uwagi

Ten konstruktor tworzy CipherReference obiekt przy użyciu identyfikatora URI (Uniform Resource Identifier) i łańcucha przekształcania w celu wskazania zaszyfrowanych danych. Następnie obiekt służy do przekazywania informacji referencyjnych dla CipherData obiektu.
