QueryClient Class

Show in webframe
Example 





Members 
An abstract layer for implementing DICOM Query operations.
Object Model
Syntax
public abstract class QueryClient 
'Declaration
 
Public MustInherit Class QueryClient 
'Usage
 
Dim instance As QueryClient

            

            
public ref class QueryClient abstract 
Remarks

Inheritors can use this class to provide an abstraction layer for their applications without the need to worry how the query is performed.

Derived classes might perform DICOM Communication queries or direct database queries.
