IStorageDataAccessAgent4 Interface

Summary

Provides methods for accessing and adding DICOM Instance information.

Syntax
C#
VB
C++
public interface IStorageDataAccessAgent4 : IStorageDataAccessAgent3, IStorageDataAccessAgent2, IStorageDataAccessAgent 
Public Interface IStorageDataAccessAgent4 
   Inherits IStorageDataAccessAgent3, IStorageDataAccessAgent2, IStorageDataAccessAgent 
public: 
   interface class IStorageDataAccessAgent4 abstract : IStorageDataAccessAgent3, IStorageDataAccessAgent2,  
    IStorageDataAccessAgent
Remarks

The IStorageDataAccessAgent4 interface derives from the IStorageDataAccessAgent3, IStorageDataAccessAgent2, and IStorageDataAccessAgent interfaces. The functionality in the IStorageDataAccessAgent4 interface that is not part of the derived interfaces is related to generating, storing, and deleting DICOM XML and JSON metadata.

Example

This example uses all available metadata operations on the IStorageDataAccessAgent4 interface.
