Metaclass Field Extends Feature, Variable Description A feature whose value is a part of the state of an object or class, e.g. an attribute or association Refs StructuralFeature [5, p. 2-14, Figure 2-5], [5, pp. 2-54, 2-69] AssociationEnd redefines Description Any inherited fields overridden (redefined) by this field Type Set (Field) Multiplicity * Attribute implicitRedefinition Description Does the field represent an implicit redefinition (e.g., to match a particular language semantics) rather than a redefinition explicitly specified by the user? Type Boolean DefaultValue false Attribute multiplicity Description The number of values that the feature may hold, typically specified as a range (min .. max) or ‘*’ (zero or more). In the common case in which the multiplicity is 1..1, the feature is a scalar. Type Multiplicity Attribute ordering Description Are the values associated with the feature ordered? Type OrderingKind
