InnerTableLink

class InnerTableLink<SID : Any, Source : Entity<SID>, ID : Any, Target : Entity<ID>>(val table: Table, sourceTable: IdTable<SID>, val target: EntityClass<ID, Target>, _sourceColumn: Column<EntityID<SID>>? = null, _targetColumn: Column<EntityID<ID>>? = null) : ReadWriteProperty<Source, SizedIterable<Target>>

Class responsible for implementing property delegates of the read-write properties involved in a many-to-many relation, which uses an intermediate (join) table.

Parameters

table

The intermediate table containing reference columns to both child and parent entities.

sourceTable

The IdTable associated with the source child entity.

target

The EntityClass for the target parent entity.

_sourceColumn

The intermediate table's reference column for the child entity class. If left null, this will be inferred from the provided intermediate table columns.

_targetColumn

The intermediate table's reference column for the parent entity class. If left null, this will be inferred from the provided intermediate table columns.
