ComposedRelationship

trait ComposedRelationship[Owner <: (RelationshipCompositionComponent.this)#EntityTable[O, I1], Join <: (RelationshipCompositionComponent.this)#EntityTable[J, _], To <: slick.driver.JdbcProfile.API.Table[T], O <: (RelationshipCompositionComponent.this)#Entity[O, I1], J <: (RelationshipCompositionComponent.this)#Entity[J, _], T, I1, C[_], C1[_], C2[_]] extends (RelationshipCompositionComponent.this)#Relationship[Owner, To, O, I1, T, C]

Composes a base relationship from an owner entity to a joining entity, with an attached relationship from the joining entity to a target relation, into a relationship from the owner entity to the target relation.

Owner

The owner entity's table type.

Join

To

The target relation's table type.

O

The owner entity's type.

J

The joining entity's type.

T

The target relation's type.

I1

The owner entity's ID type.

C

The type of the functor containing target relation values that are retrieved from the database.

C1

The type of the functor containing retrieved values for the base relationship.

C2

The type of the functor containing retrieved values for the attached relationship.
