RetrieveClient Class

Summary

An abstract layer for implementing DICOM Retrieve operations.

Syntax

C++

public abstract class RetrieveClient : BaseClient

Public MustInherit Class RetrieveClient 
   Inherits 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.
