C# Class Opc.Ua.EndpointBase.ProcessRequestAsyncResult

An AsyncResult object when handling an asynchronous request.

Inheritance: AsyncResultBase, IEndpointIncomingRequest

ファイルを表示 Open project: OPCFoundation/UA-.NETStandardLibrary

Public Methods

Method	Description
BeginProcessRequest ( SecureChannelContext context, IServiceRequest request ) : IAsyncResult	Begins processing an incoming request.
BeginProcessRequest ( SecureChannelContext context, byte requestData ) : IAsyncResult	Begins processing an incoming request.
CallSynchronously ( ) : void	Used to call the default synchronous handler. This method may block the current thread so the caller must not call in the thread that calls IServerBase.ScheduleIncomingRequest(). This method always traps any exceptions and reports them to the client as a fault.
GetRequest ( IAsyncResult ar ) : IServiceRequest	Checks for a valid IAsyncResult object and returns the original request object.
OperationCompleted ( IServiceResponse response, ServiceResult error ) : void	Used to indicate that the asynchronous operation has completed.
ProcessRequestAsyncResult ( EndpointBase endpoint, AsyncCallback callback, object callbackData, int timeout ) : System	Initializes a new instance of the ProcessRequestAsyncResult class.
WaitForComplete ( IAsyncResult ar, bool throwOnError ) : IServiceResponse	Checks for a valid IAsyncResult object and waits for the operation to complete.

Private Methods

Method	Description
OnProcessRequest ( object state ) : void	Processes the request.
SaveExceptionAsResponse ( Exception e ) : IServiceResponse	Saves an exception as response.

Method Details

BeginProcessRequest() public method

Begins processing an incoming request.

public BeginProcessRequest ( SecureChannelContext context, IServiceRequest request ) : IAsyncResult
context	SecureChannelContext	The security context for the request
request	IServiceRequest	The request.
return	IAsyncResult

BeginProcessRequest() public method

Begins processing an incoming request.

public BeginProcessRequest ( SecureChannelContext context, byte requestData ) : IAsyncResult
context	SecureChannelContext	The security context for the request
requestData	byte	The request data.
return	IAsyncResult

CallSynchronously() public method

Used to call the default synchronous handler.

This method may block the current thread so the caller must not call in the thread that calls IServerBase.ScheduleIncomingRequest(). This method always traps any exceptions and reports them to the client as a fault.

public CallSynchronously ( ) : void
return	void

GetRequest() public static method

Checks for a valid IAsyncResult object and returns the original request object.

public static GetRequest ( IAsyncResult ar ) : IServiceRequest
ar	IAsyncResult	The IAsyncResult object for the operation.
return	IServiceRequest

OperationCompleted() public method

Used to indicate that the asynchronous operation has completed.

public OperationCompleted ( IServiceResponse response, ServiceResult error ) : void
response	IServiceResponse	The response. May be null if an error is provided.
error	ServiceResult
return	void

ProcessRequestAsyncResult() public method

Initializes a new instance of the ProcessRequestAsyncResult class.

public ProcessRequestAsyncResult ( EndpointBase endpoint, AsyncCallback callback, object callbackData, int timeout ) : System
endpoint	EndpointBase	The endpoint being called.
callback	AsyncCallback	The callback to use when the operation completes.
callbackData	object	The callback data.
timeout	int	The timeout in milliseconds
return	System

WaitForComplete() public static method

Checks for a valid IAsyncResult object and waits for the operation to complete.

public static WaitForComplete ( IAsyncResult ar, bool throwOnError ) : IServiceResponse
ar	IAsyncResult	The IAsyncResult object for the operation.
throwOnError	bool	if set to true an exception is thrown if an error occurred.
return	IServiceResponse
