FindCodedConcept Method

Summary

Returns the Coded Concept, in the specified Context Group, which has the specified Coding Scheme Designator and Code Value.

Syntax

Objective-C

C++/CLI

public DicomCodedConcept FindCodedConcept( 
   DicomContextGroup contextGroup, 
   string codingSchemeDesignator, 
   string codeValue 
)

- (nullable LTDicomCodedConcept *)findCodedConcept:(LTDicomContextGroup *)contextGroup codingSchemeDesignator:(NSString *)codingSchemeDesignator codeValue:(NSString *)codeValue NS_SWIFT_NAME(findCodedConcept(group:codingSchemeDesignator:codeValue:));

public: 
DicomCodedConcept^ FindCodedConcept(  
   DicomContextGroup^ contextGroup, 
   String^ codingSchemeDesignator, 
   String^ codeValue 
)

Parameters

contextGroup
Specifies the Context Group to be searched for the Coded Concept.

codingSchemeDesignator
The Coding Scheme Designator (0008,0102) of the Coded Concept.

codeValue
The Code Value (0008,0100) of the Coded Concept.

Return Value

DicomCodedConcept object that specifies the Coded Concept in the specified Context Group that has the specified Coding Scheme Designator and Code Value. null, The specified Context Group does not contain a Coded Concept with the specified Coding Scheme Designator and Code Value.

Remarks

A Coded Concept is identified in its Context Group by its Coding Scheme Designator (0008,0102) and Code Value (0008,0100). Use the FindCodedConcept method to search a Context Group for a specific Coded Concept.
To search for a specific Context Group in the Context Group Table, use the Find method.
