klyn.data.EntityManager.find
method
public find<T, TId>(id as TId) as T:
Description

Finds an entity by its mapped identity.

The identity map is consulted before provider I/O. Repeated calls and KQL materialization therefore return the same managed instance. The compiler accepts find<T>(id) and infers TId from @Id.

Parameters
ParameterDescription
<T>Entity type.
<TId>Effective identity type.
idIdentity to find.
Returns

Managed entity, or null when absent.

Throws
  • EntityMappingException when the key type does not match.
Example
user = manager.find<User>(42)
if user is not null:
print(user.login)
