RecordComputeExtension4<T1, T2, T3, T4> extension

Extends a record with a method for creating a ComputeCell by applying a function on the argument cells given in the record.

on

• (ValueCell<T1>, ValueCell<T2>, ValueCell<T3>, ValueCell<T4>)

Methods

apply<U>(U fn(T1, T2, T3, T4), {dynamic key}) → ValueCell<U>

Create a ComputeCell with compute function fn with the cells in this as the argument list.

mutableApply<U>(U fn(T1, T2, T3, T4), void reverse(U), {dynamic key, bool changesOnly = false}) → MutableCell<U>

Create a MutableComputeCell with given compute and reverse compute functions, and the cells in this as the argument list.
