QueryClient Class

Summary

An abstract layer for implementing DICOM Query operations.

Syntax

C++

public abstract class QueryClient

Public MustInherit Class 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.
