Begins an asynchronous operation to cancel a security token.
protected:
virtual IAsyncResult ^ BeginCancelTokenCore(TimeSpan timeout, System::IdentityModel::Tokens::SecurityToken ^ token, AsyncCallback ^ callback, System::Object ^ state);protected virtual IAsyncResult BeginCancelTokenCore (TimeSpan timeout, System.IdentityModel.Tokens.SecurityToken token, AsyncCallback callback, object state);abstract member BeginCancelTokenCore : TimeSpan * System.IdentityModel.Tokens.SecurityToken * AsyncCallback * obj -> IAsyncResult
override this.BeginCancelTokenCore : TimeSpan * System.IdentityModel.Tokens.SecurityToken * AsyncCallback * obj -> IAsyncResultProtected Overridable Function BeginCancelTokenCore (timeout As TimeSpan, token As SecurityToken, callback As AsyncCallback, state As Object) As IAsyncResultParameters
- timeout
- TimeSpan
A TimeSpan that specifies the timeout value for the message that cancels the security token.
- token
- SecurityToken
The SecurityToken to cancel.
- callback
- AsyncCallback
The AsyncCallback delegate that receives notification of the completion of the asynchronous close operation.
- state
- Object
An object, specified by the application, that contains state information associated with the asynchronous close operation.
Returns
The IAsyncResult that references the asynchronous cancel operation.
Remarks
A security token that can be cancelled, such as one that is issued, allows a client that requested a security token to cancel it when it is done with it.
Notes to Inheritors
When you inherit from the SecurityTokenProvider class you are not required to override the asynchronous methods, as the SecurityTokenProvider base class provides asynchronous support based upon the synchronous methods. Therefore, you are not required to override the BeginCancelTokenCore(TimeSpan, SecurityToken, AsyncCallback, Object) method, unless you need to provide your own asynchronous implementation.
The BeginCancelTokenCore(TimeSpan, SecurityToken, AsyncCallback, Object) method is called by the BeginCancelToken(TimeSpan, SecurityToken, AsyncCallback, Object) method.
The asynchronous methods, which have a prefix of Begin and End, do not need to be overridden in derived classes. The SecurityTokenProvider base class provides an asynchronous implementation that is based on the synchronous methods.
