groupByComputed<K2> abstract method

ComputedMap<K2, ComputedMap<K, V>> groupByComputed<K2>(
  1. Computed<K2> key(
    1. K key,
    2. V value
    )
)

As with groupBy, but groups the elements by the reactive value of a computation.

Implementation

ComputedMap<K2, ComputedMap<K, V>> groupByComputed<K2>(
    Computed<K2> Function(K key, V value) key);
