ComplexValueList

open class ComplexValueList : ListBase, Codable, ComplexValueOrList, Sequence, @unchecked Sendable

A list of item type ComplexValue.

  • Decode and initialize a new object instance

    Declaration

    Swift

    public required init(from decoder: Decoder) throws

    Parameters

    from

    decoder object which contains the original object’s serialized data in a container instance

  • Encode the object instance

    Declaration

    Swift

    public func encode(to encoder: Encoder) throws

    Parameters

    to

    encoder object which can be used to serialize the object’s data one by one into a container instance

  • Undocumented

    Declaration

    Swift

    public subscript(index: Int) -> ComplexValue { get set }

  • An immutable empty ComplexValueList.

    Declaration

    Swift

    public static let empty: ComplexValueList

  • true if this list is a referece. If true, the readLink will be non-null, and this list will be empty.

    Declaration

    Swift

    final public var isReference: Bool

  • An optional link that can be followed (by the caller) to fetch additional list items. If this complex list was produced via server-driven paging, then the server may have provided a next-link which can be followed to obtain more items.

    Declaration

    Swift

    final public var nextLink: String?

  • An optional link that can be followed (by the caller) to re-read this list.

    Declaration

    Swift

    final public var readLink: String?

  • Total number of items available in the server-side list, which may be greater than length if the client requested an inline DataQuery.count.

    Declaration

    Swift

    final public var totalCount: Int64?

  • Construct a new list with length of zero and optional initial capacity. A list can expand in length beyond its initial capacity, but best performance will be obtained if the initial capacity is close to (and not less than) the list’s maximum length.

    Declaration

    Swift

    override public init(capacity: Int = (4 as Int))

    Parameters

    capacity

    Optional initial capacity.

  • Add item to the end of this list.

    Declaration

    Swift

    public final func append(_ item: ComplexValue)

    Declaration

    Swift

    public final func append(contentsOf list: ComplexValueList)

    Parameters

    list

    Items to be added.

    Declaration

    Swift

    open func appendOptional(_ item: ComplexValue?) -> ComplexValueList

    Parameters

    item

    Item to be added, which might be nil.

    Return Value

    Parameters

    query

    Data query whose DataQuery.pageSize is used for filtering.

    Return Value

    A new list with at most query.pageSize initial items of this list. The result’s ComplexValueList.needsNextLink will be true if the original list length exceeded the page size.

    Swift

    public final func copy() -> ComplexValueList

    Return Value

    A shallow copy of this list.

  • Declaration

    Swift

    override open func copyMutable() -> DataValue

    Return Value

    A clone of this value if it (together with all value subcomponents) is possibly mutable, or return self value if it (together with all value subcomponents) is definitely immutable. The resulting value might share mutable metadata with this query.
