Class UML 2.3::Operation
Description:
Operation specializes TemplateableElement in order to support specification
of template operations and bound operations. Operation specializes ParameterableElement
to specify that an operation can be exposed as a formal template parameter,
and provided as an actual parameter in a binding of a template.

ElementConstraints:
Signature: CMOF_14_3_17a() : Boolean;
Description: 14.3 [17] An Operation can have up to one Parameter whose direction is 'return';
furthermore, an Operation cannot have any ParameterSet per 12.4 [8].
Expression: ownedParameter->select(direction = ParameterDirectionKind::return)->size() < 2 and
ownedParameterSet->isEmpty()
Signature: CMOF_14_3_2() : Boolean;
Description: 14.3 [2] The type of Operation::raisedException is limited to be Class rather than Type.

Expression: raisedException->forAll(e | e.oclIsTypeOf(Class))
Signature: only_body_for_query() : Boolean;
Description: A bodyCondition can only be specified for a query operation.
Expression: bodyCondition->notEmpty() implies isQuery
Signature: at_most_one_return() : Boolean;
Description: An operation can have at most one return parameter; i.e., an owned parameter
with the direction set to 'return'
Expression: self.ownedParameter->select(par | par.direction = #return)->size() <= 1
Operations:
Signature: upper.1() : UnlimitedNatural;
Description: If this operation has a return parameter, upper equals the value of upper for that parameter. Otherwise upper is not defined.
Expression: result = if returnResult()->notEmpty() then returnResult()->any().upper else Set{} endif
Signature: type.1() : Type;
Description: If this operation has a return parameter, type equals the value of type for that parameter. Otherwise type is not defined.
Expression: result = if returnResult()->notEmpty() then returnResult()->any().type else Set{} endif
Signature: returnResult() : Parameter;
Description: The query returnResult() returns the set containing the return parameter of the Operation if one exists, otherwise, it returns an empty set
Expression: result = ownedParameter->select (par | par.direction = #return)
Signature: lower.1() : Integer;
Description: If this operation has a return parameter, lower equals the value of lower for that parameter. Otherwise lower is not defined.
Expression: result = if returnResult()->notEmpty() then returnResult()->any().lower else Set{} endif
Signature: isUnique.1() : Boolean;
Description: If this operation has a return parameter, isUnique equals the value of isUnique for that parameter. Otherwise isUnique is true.
Expression: result = if returnResult()->notEmpty() then returnResult()->any().isUnique else true endif
Signature: isOrdered.1() : Boolean;
Description: If this operation has a return parameter, isOrdered equals the value of isOrdered for that parameter. Otherwise isOrdered is false.
Expression: result = if returnResult()->notEmpty() then returnResult()->any().isOrdered else false endif
Signature: isConsistentWith(redefinee : RedefinableElement; ) : Boolean;
Description: A redefining operation is consistent with a redefined operation if it has the same number of owned parameters, and the type of each owned parameter conforms to the type of the corresponding redefined parameter.
The OCL used here is not normative.Editor's notes: Needs investigation
Expression: true
Original: result = redefinee.oclIsKindOf(Operation) and
let op : Operation = redefinee.oclAsType(Operation) in
self.ownedParameter->size() = op.ownedParameter->size() and
Sequence{1 ..self.ownedParameter->size()}->
forAll(i |op.ownedParameter->at(1).type.conformsTo(self.ownedParameter->at(i).type))
