    • mapValues

      @NotNull @Support <T> @NotNull CaseWhenStep<V,T> mapValues(Map<V,T> values)
      Create WHEN … THEN expressions from a Map.

      This will iterate over the map's entries to create individual WHEN … THEN expressions for each map entry.

    • mapFields

      @NotNull @Support <T> @NotNull CaseWhenStep<V,T> mapFields(Map<? extends Field<V>,? extends Field<T>> fields)
      Create WHEN … THEN expressions from a Map.

      This will iterate over the map's entries to create individual WHEN … THEN expressions for each map entry.
