    \brief An operation is a behavioral feature of a classifier that specifies the name, type, parameters, and constraints for invoking an associated behavior.An operation may invoke both the execution of method behaviors as well as other behavioral responses.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.

/*!
    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 query isConsistentWith() specifies, for any two Operations in a context in which redefinition is possible, whether redefinition would be consistent in the sense of maintaining type covariance. Other senses of consistency may be required, for example to determine consistency in the sense of contravariance. Users may define alternative queries under names different from 'isConsistentWith()', as for example, users may define a query named 'isContravariantWith()'.
