A behavioral feature is a feature of a classifier that specifies an aspect of the behavior of its instances.
Description
A behavioral feature is a feature of a classifier that specifies an aspect of the behavior of its instances. BehavioralFeature
is an abstract metaclass specializing Feature and Namespace. Kinds of behavioral aspects are modeled by subclasses of BehavioralFeature.

Attributes

Associations
• / parameter: Parameter[*] — Specifies the parameters of the BehavioralFeature. Subsets Namespace::member. This is a derived
union and is ordered.
Constraints
No additional constraints
Additional Operations
[1] The query isDistinguishableFrom() determines whether two BehavioralFeatures may coexist in the same Namespace. It specifies
that they have to have different signatures.
BehavioralFeature::isDistinguishableFrom(n: NamedElement, ns: Namespace): Boolean;
isDistinguishableFrom =if n.oclIsKindOf(BehavioralFeature)then
if ns.getNamesOfMember(self)->intersection(ns.getNamesOfMember(n))->notEmpty()then Set{}->including(self)->including(n)->isUnique( bf | bf.parameter->collect(type))else trueendif
else trueendif
Semantics
The list of parameters describes the order and type of arguments that can be given when the BehavioralFeature is invoked.
