A classifier is a category s. A classifier is an abstract metaclass classification concept that serves as a mechanism to show interfaces, classes, datatypes and components. A classifier describes a set of instances that have common behavioral and structural features (operations and attributes, respectively). A classifier is a namespace whose members can specify a generalization hierarchy by referencing its general classifiers. A classifier is a type and can own generalizations, thereby making it possible to define generalization relationships to other classifiers. A classifier is a redefinable element, as it is possible to redefine nested classifiers. All objects that can have instances are classifiers. ==Important Aspects== *A classifier defines a namespace. *A classifier contains a set of features. *A classifier is generalizable. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Classifier (UML)」の詳細全文を読む スポンサード リンク
