FindModuleByIndex Method

Summary

Returns the item in the IOD Structure that contains the IOD for the module in the specified class at the specified index.

Syntax

Objective-C

C++/CLI

Java

public DicomIod FindModuleByIndex( 
   DicomClassType type, 
   int index 
)

- (nullable LTDicomIod *)findModule:(LTDicomClassType)type byIndex:(NSUInteger)index;

public DicomIod findModuleByIndex(DicomClassType type, int index)

public: 
DicomIod^ FindModuleByIndex(  
   DicomClassType type, 
   int index 
)

Parameters

type
The class in which to look for the module.

index
Value that indicates the position of the module within the class. This index is zero-based. For example, if nIndex is 2 and class is DicomClassType.NMImageStorage, this method will return the item in the IOD Structure that contains the IOD for the module at index position 2 in the Nuclear Medicine Image class.

Return Value

DicomIod class in the IOD Structure that contains the IOD for the module at the specified index position in the specified class.

Remarks

To find the IOD of a module within a class use FindModule. To find the IOD for a specific class use FindClass.
Find lets you find IODs for classes, modules or elements in the IOD Structure.

using Leadtools.Dicom;

   // We can in here call any of the Find methods including FindModule and FindModuleByIndex, 
   // in this sample we are searching for a DICOM class, this is why we are using FindClass

   string name = iod.ToString();
