Function
iterate(_:_:_:)
Accumulates elements of a collection using the given accumulator function.
func iterate(_ collection: any EcoreValue, _ initial: any EcoreValue, _ accumulator: (any EcoreValue, any EcoreValue) throws -> any EcoreValue) throws -> any EcoreValueParameters
collection-
The collection to iterate over
initial-
The initial value for the accumulation
accumulator-
A closure that takes the current accumulated value and an element
Return Value
The final accumulated value
Discussion
The iterate operation performs a fold/reduce operation, starting with an initial value and applying the accumulator function to each element in sequence.
Examples
let numbers = [1, 2, 3, 4] as [EInt]
let sum = try iterate(numbers, 0 as EInt) { acc, elem in
(acc as? EInt ?? 0) + (elem as? EInt ?? 0)
}
// Result: 10
