SetAsynchronousOperations Method

Summary

Enables or disables Asynchronous Operation support. It also sets the number of operations that can be invoked, if enabled.

Syntax

Objective-C

C++/CLI

public void SetAsynchronousOperations( 
   bool enabled, 
   int invokedCount, 
   int performedCount 
)

- (BOOL)setAsynchronousOperations:(BOOL)enabled invokedCount:(NSUInteger)invokedCount performedCount:(NSUInteger)performedCount error:(NSError **)error NS_SWIFT_NAME(setAsynchronousOperations(enabled:invokedCount:performedCount:));

public: 
void SetAsynchronousOperations(  
   bool enabled, 
   int invokedCount, 
   int performedCount 
)

Parameters

enabled
true to enable Asynchronous Operations; otherwise, false.

invokedCount
The number of operations (messages) that can be sent without a response.

performedCount
The number of Asynchronous Operations performed.

Remarks

If a DICOM Associate connection does not support Asynchronous Operations, then an Application Entity must wait for the response from one message before sending another. If Asynchronous Operations are supported, multiple messages may be sent without waiting for a response. The number of messages that may be sent is set using SetAsynchronousOperations. InvokedOperationsCount specifies the number of Asynchronous Operations that may be invoked without a response. PerformedOperationsCount specifies the number of operations that have been completed.

Example

using Leadtools; 
using Leadtools.Dicom; 
 
 
void BuildVerifyAssociate() 
{ 
   //Make sure to initialize the DICOM engine, this needs to be done only once  
   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomAssociate associate = new DicomAssociate(true)) 
   { 
      //Role Select 
      associate.AddPresentationContext(1, 0, DicomUidType.VerificationClass); 
      associate.SetRoleSelect(1, true, DicomRoleSupport.Supported, DicomRoleSupport.Unsupported); 
      Debug.Assert(associate.IsRoleSelect(1) == true); 
      Debug.Assert(associate.GetUserRole(1) == DicomRoleSupport.Supported); 
      Debug.Assert(associate.GetProviderRole(1) == DicomRoleSupport.Unsupported); 
 
      //Extended Data 
      associate.SetExtendedData(1, new byte[] { 55 }); 
      Debug.Assert(associate.GetExtendedDataLength(1) == 1); 
      byte[] extendedData = associate.GetExtendedData(1); 
      Debug.Assert(extendedData[0] == 55); 
      // We can also call GetExtendedDataPtr 
 
      //Asynchronous Operations 
      associate.SetAsynchronousOperations(true, 5, 5); 
      Debug.Assert(associate.IsAsynchronousOperations == true); 
      Debug.Assert(associate.InvokedOperationsCount == 5); 
      Debug.Assert(associate.PerformedOperationsCount == 5); 
 
      //User Information 
      associate.AddUserInformation(4, new byte[] { 88 }); 
      Debug.Assert(associate.UserInformationCount == 1); 
      Debug.Assert(associate.GetUserInformationType(0) == 4); 
      Debug.Assert(associate.GetUserInformationDataLength(0) == 1); 
      Debug.Assert(associate.GetUserInformationDataPtr(0) != null); 
      byte[] userInformationData = associate.GetUserInformationData(0); 
      Debug.Assert(userInformationData[0] == 88); 
      associate.SetUserInformation(0, 3, new byte[] { 56 }); 
      userInformationData = associate.GetUserInformationData(0); 
      Debug.Assert(userInformationData[0] == 56); 
      associate.DeleteUserInformation(0); 
   } 
   DicomEngine.Shutdown(); 
}
