Kas saaksite selgitada, mida tähendab termin 'Wrapped' programmeerimise või arendamise kontekstis?

In programming, the term «Wrapped» (encapsulated) means that one object or value is placed inside another, usually to add additional behavior, control, or to simplify working with them.

For example, in iOS, the wrapping pattern is often used, where an optional type (Optional) is «wrapped» into a safe type with a default value — this is called Wrapped Value. In SwiftUI, there is a property @State with a wrappedValue, which allows working with the internal value of the property.

Example of wrapping in Swift:

struct Wrapper {
    private var value: Int
    var wrappedValue: Int {
        get { value }
        set { value = newValue }
    }
    init(_ value: Int) {
        self.value = value
    }
}

var wrapped = Wrapper(10)
print(wrapped.wrappedValue) // 10
wrapped.wrappedValue = 20
print(wrapped.wrappedValue) // 20

Thus, «wrapped» is an object that encapsulates another value or object inside itself, adding an extra layer of abstraction or functionality.
