User Manual [Previous] [Next]
Inline Associations
An association represents a relationship between two classes. Associations can be defined within a class, in a similar manner as you would define an attribute.
Contrast this with the same model defined using independently defined associations.
Example
class Group
{
// a many-to-many association
// An item has zero or more groups and a group
// has zero or more items
* -- * Item;
// An item has an optional description
// The association is directed, so descriptions
// do not know which groups link to them
1 -> 0..1 Description;
}
class Item
{}
class Description
{}
