Parametri

serializationStream
Stream Stream Stream Stream

Flusso in cui serializzare il grafico.The stream to which the graph is to be serialized.

graph
Object Object Object Object

Oggetto alla radice del grafico da serializzare.The object at the root of the graph to serialize.

Implementazioni

Eccezioni

L'elemento serializationStream è null.The serializationStream is null.

In alternativa-or- graph è Null.The graph is null.

Si è verificato un errore durante la serializzazione, ad esempio un oggetto nel parametro graph non è contrassegnato come serializzabile.An error has occurred during serialization, such as if an object in the graph parameter is not marked as serializable.

Il chiamante non dispone dell'autorizzazione richiesta.The caller does not have the required permission.
