WeakArray

public class WeakArray<T>

A Collection similar to an array, but wraps its Elements in a WeakRef.

  • Initialize an empty WeakArray

    Declaration

    Swift

    public init()

  • Add an object reference to the array

    Declaration

    Swift

    public func add(object: T)

    Parameters

    object

    the object to weak reference before adding it to the array

  • Dereference the object at index when not released

    Declaration

    Swift

    public func object(at index: Int) -> T?

    Parameters

    index

    index to get

    Return Value

    The object when not deinitialized

  • Insert an object reference at a specified index

    Declaration

    Swift

    public func insert(object: T, at index: Int)

    Parameters

    object

    the object to weak reference before adding it to the array
    index

    the index to insert at

  • Replace a weak reference with a new object

    Declaration

    Swift

    public func replaceObject(at index: Int, with object: T)

    Parameters

    index

    the index to replace
    object

    the object to weak reference before replacing the reference at index

  • Remove an object reference at a specified index

    Declaration

    Swift

    public func removeObject(at index: Int)

    Parameters

    index

    index of the reference to remove

  • Get the current count of available (not-released) object references

    Note

    complexity O(n) - since we filter out the zeroed WeakRefs

    Declaration

    Swift

    public var count: Int { get }

    Return Value

    the current active reference count

  • Dereference the object at index when not released

    See

    object(at:)

    Declaration

    Swift

    public subscript(index: Int) -> T? { get }

    Parameters

    index

    index to get

    Return Value

    The object when not deinitialized

  • Find the index of an object in the array

    Note

    complexity O(2n)

    Declaration

    Swift

    public func index(of object: T) -> Int?

    Parameters

    object

    the object to search for

    Return Value

    the index when found else nil

  • Convenience initializer for weak referencing an entire array

    Declaration

    Swift

    public convenience init(objects: [T])

    Parameters

    objects

    the object to weak reference in the newly initialized WeakArray

  • Get objects referenced by Self as a strong array

    Declaration

    Swift

    public var array: [T] { get }

    Return Value

    Array with available objects
