ForValues -> For<K, VO>

function Fusion.ForValues<K, VI, VO, S>(
    scope: Scope<S>,
    inputTable: UsedAs<{[K]: VI}>,
    processor: (Use, Scope<S>, value: VI) -> VO
) -> For<K, VO>

Constructs and returns a new For state object which processes values and preserves keys.

Use scoped() method syntax

This function is intended to be accessed as a method on a scope:

local forObj = scope:ForValues(inputTable, processor)


Parameters

scope : Scope<S>

The scope which should be used to store destruction tasks for this object.

inputTable : UsedAs<{[K]: VI}>

The table which will provide the input keys and input values for this object.

If it is a state object, this object will respond to changes in that state.

processor : (Use, Scope<S>, value: VI) -> VO

Accepts a VI value from the input table, and returns the VO value that should appear in the output table.

The processor is given a use function for including other objects in the computation, and a scope for queueing destruction tasks to run on re-computation. The given scope has the same methods as the scope used to create the whole object.


Returns -> For<K, VO>

A freshly constructed For state object.
