Mixin super-class for classes of which instances can participate in relations.
| relaters | [Slot] |
The associative list ((role . relation*)*) that contains the relations that relate this relatable, organized by the respective roles the relatables assume in the relations.
| copy | [Slot] |
When a relatable is copied using copy-object, then the copy is temporarily assigned to this slot. This copy can then be used to re-link the copy of the relations in the second pass of the copying.
| relation-class | inherits from relatable-class | [Class] |
A relation relates one or more relatables, each one under a unique role. Example instantiation: (make-instance 'relation :relatees `((parent ,a-parent) (child ,a-child))
| :relatees | [Initarg] |
| relatees | [Slot] |
The associative list ((role . relatable)*) that contains the relatees related by this relation, organized by their roles.
Returns and (with setf) changes the copy of the specified relatable-struct
Role equality function, can be specialized for special roles.
Remove a relatee from the given relation, where the to be removed relatable participates in the relation under the given role.
Return the relations that relate the given relatable. If a role is given then only those relations that relate this relatable under the given role are returned. If a typespec is given than only those relations that are of that given type are returned. A role and a typespec can be combined.
Add the given relation to the collection of relations that relate this relatable. Warning: this method should typically not be called by users. Users should typically call add-relatee, which calls add-relater.
Removes the given relation from the collection of relations that relate this relatable. A role can be given when the relatable is related multiple times by the same relation under different roles.
