Méthodes publiques

Méthode Description
Activate ( OperationContext context, List clientSoftwareCertificates, UserIdentityToken identityToken, IUserIdentity identity, IUserIdentity effectiveIdentity, StringCollection localeIds, byte serverNonce ) : bool

Activates the session and binds it to the current secure channel.
Close ( ) : void

Closes a session and removes itself from the address space.
Dispose ( ) : void

Frees any unmanaged resources.
IsSecureChannelValid ( string secureChannelId ) : bool

Checks if the secure channel is currently valid.
RestoreContinuationPoint ( byte continuationPoint ) : ContinuationPoint

Restores a continuation point for a session.

The caller is responsible for disposing the continuation point returned.

RestoreHistoryContinuationPoint ( byte continuationPoint ) : object

Restores a previously saves history continuation point.
SaveContinuationPoint ( ContinuationPoint continuationPoint ) : void

Saves a continuation point for a session.

If the session has too many continuation points the oldest one is dropped.

SaveHistoryContinuationPoint ( System.Guid id, object continuationPoint ) : void

Saves a continuation point used for historical reads.

If the continuationPoint implements IDisposable it will be disposed when the Session is closed or discarded.

UpdateLocaleIds ( StringCollection localeIds ) : bool

Updates the requested locale ids.
ValidateBeforeActivate ( OperationContext context, SignatureData clientSignature, List clientSoftwareCertificates, ExtensionObject userIdentityToken, SignatureData userTokenSignature, StringCollection localeIds, byte serverNonce, UserIdentityToken &identityToken, UserTokenPolicy &userTokenPolicy ) : void

Activates the session and binds it to the current secure channel.
ValidateRequest ( RequestHeader requestHeader, RequestType requestType ) : void

Validates the request.

Méthodes protégées

Méthode Description
Dispose ( bool disposing ) : void

An overrideable version of the Dispose.
