SetDateValue(DicomElement,DicomDateValue[]) Method

Summary

Sets the Date values of a Data Element.

Syntax

C++/CLI

Java

public bool SetDateValue( 
   DicomElement element, 
   DicomDateValue[] value 
)

public boolean setDateValue(DicomElement element, DicomDateValue[] values)

public: 
bool SetDateValue(  
   DicomElement^ element, 
   array<DicomDateValue>^ value 
)

Parameters

element
An item in the Data Set.

value
Pointer to an array of DicomDateValue objects that contain the Date value(s) to set.

Return Value

true if the Date values were set successfully; otherwise, it is false (the Date values of the Data Element could not be set).

Remarks

This method can be called only if the Value Representation of the Data Element is DicomVRType.DA. For more information about Value Representations, refer to Default Value Representation Table.
