edmiRemoteGetAttrPrimitiveType

 
Returns the required primitive type of the data values to be assigned to a specified attribute.
Related function: edmiRemoteGetAttrPrimitiveTypeBN
Header:
#include "sdai.h"
Prototype:
EdmiError edmiRemoteGetAttrPrimitiveType(SdaiServerContext serverContextId,
                                          SdaiAttr          attributeId, 
                                          SdaiPrimitiveType *dataType, 
                                          SdaiInvocationId *edmiInvocationId);
 
Arguments:

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an _EDMinterface^_ error code. Use edmiGetErrorText to get the error text corresponding to the error code.
Example:
EdmiError rstat;
SdaiServerContext myContext;
SdaiRepository repositoryId;
SdaiModel modelId;
SdaiEntity entityId;
SdaiString entityName;
SdaiInstance instId;
SdaiAttr attrId;
SdaiPrimitiveType attrType;
SdaiString stringId = "721212";
SdaiInteger integerId = 721212;
SdaiVoid value;
