edmiIsAggrSubset

EdmiError edmiIsAggrSubset(SdaiAggr    operand1,
                            SdaiAggr    operand2, 
                            SdaiLogical *result);

This operation implements the aggregate subset operation in the Express language, defined in 12.6.5 Subset operator in ISO 10303-11:1994(E) : The EXPRESS Language Reference Manual. The data model(s) that hosts the two specified aggregates must be open before this operation can be successfully performed.

Arguments

Type	Name	Comment
SdaiAggr	operand1	A numeric aggregateID that uniquely identifies the aggregate instance used as the left operand (operand1) in the aggregate subset operation. The aggregateID is returned when the aggregate is created or it can be retrieved with an EDMinterface get operation.
SdaiAggr	operand2	A numeric aggregateID that uniquely identifies the aggregate instance used as the right operand (operand2) in the aggregate subset operation. The aggregateID is returned when the aggregate is created or it can be retrieved with an EDMinterface get operation..
SdaiLogical	result	Address of a SdaiLogical variable that will receive the result of the aggregate subset operation. The result is as follows: sdaiTRUE: the compared instance values are identical sdaiFALSE: the compared instance values are not identical. sdaiUNKNOWN: use sdaiErrorQuery to check for possible error in operation.

Return Value
