Arguments
...
| Type | Name | Comment | ||
| SdaiInstance | instance | A numeric id that uniquely identifies an instance in the EDMdatabase operated by the EDM Server. | ||
| SdaiString | attributeName | The name of the attribute to read. In the cases of multipple attribute inheritance, the attribute name must be qualified with the entity name of the supertype from which the attribute was inherited. | ||
| SdaiPrimitiveType | valueType | An SdaiPrimitiveType that is assignment compatible with the declared attribute type in the related EXPRESS schema. See decalaration of SdaiPrimitiveType in file sdai.h. | The SdaiPrimitiveType, sdaiAGGR, can not be used as value type. sdaiSELECT may be used to read all data types. sdaiADB may be used to read all data types except typed values. | sdaiINTEGER is compatible with sdaiREAL, and sdaiBOOLEAN is compatible with sdaiLOGICAL, hence conversion between these compatible data types will be performed when required. |
| void | value | The value to assign to <attributeName> in <instance>. The type of <value> must be the same as specified in <valueType>. |
