EdgeDB.Object​

An immutable representation of an object instance returned from a query.

EdgeDB.Object implements Access behavior to access properties by key.

Copy

Links and links properties​


In EdgeDB, objects can have links to other objects or a set of objects. You can use the same syntax to access links values as for object
                    properties. Links can also have their own properties (denoted as @<link_prop_name> in EdgeQL syntax). You can use the same property name as
                    in the query to access them from the links.
