Description
A property is a typed element that represents an attribute of a class.
Attributes
Semantics
A property represents an attribute of a class. A property has a type and a multiplicity. When a property is paired with an
opposite they represent two mutually constrained attributes. The semantics of two properties that are mutual opposites are
the same as for bidirectionally navigable associations in Constructs, with the exception that the association has no explicit
links as instances, and has no name.
Notation
When a Basic::Property has no opposite, its notation is the same for Constructs::Property when used as an attribute with
the omission of those aspects of the notation that cannot be represented by the Basic model. Normally if the type of the
property is a data type the attribute is shown within the attribute compartment of the class box, and if the type of the
property is a class it is shown using the association-like arrow notation.
When a property has an opposite, the pair of attributes are shown using the same notation as for a Constructs::Association
with two navigable ends, with the omission of those aspects of the notation that cannot be represented by the Basic model.
