RetrieveClient Class

Summary
An abstract layer for implementing DICOM Retrieve operations.
Syntax
C#
C++/CLI
public abstract class RetrieveClient : BaseClient 
public: 
   ref class RetrieveClient abstract : BaseClient 
Remarks

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

Derived classes might perform DICOM Communication or any custom method to retrieve the images.
