lookup<V2> abstract method

ComputedMap<K, (V, V2?)> lookup<V2>(
  1. ComputedMap<K, V2> other
)

Returns the left join of this ComputedMap with other as a ComputedMap.

The returned map has the same set of keys as this. The values are records containing the corresponding values from both maps, and null, if the key does not exist on other.

Implementation

ComputedMap<K, (V, V2?)> lookup<V2>(ComputedMap<K, V2> other);
