SdbJoinTarget<JK extends SdbKey, JV extends SdbValue> class abstract

What a join key is matched against.

Either a store, on its primary key (at most one record per key), or an index, on its index key (any number of records per key, a source record then giving one row per match).

It is exactly one of the two by construction: a join method takes one required SdbJoinTarget, so passing neither or both is a compile error rather than something failing at run time.

Build one with SdbJoinTarget.store / SdbJoinTarget.index, or with the asJoinTarget getter on a store or an index ref.

Constructors

SdbJoinTarget.index(SdbIndexRef<JK, JV, SdbIndexKey> index)

Match the join key against index.

factory

SdbJoinTarget.store(SdbStoreRef<JK, JV> store)

Match the join key against the primary key of store.
