ParameterList

open class ParameterList : ListBase, Sequence

A list of item type Parameter.

  • Undocumented

    Declaration

    Swift

    public subscript(index: Int) -> Parameter { get set }
  • An immutable empty ParameterList.

    Declaration

    Swift

    public static let empty: ParameterList
  • 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 a formal parameter.

    with.

    Declaration

    Swift

    open func addFormal(name: String, type: DataType)

    Parameters

    name

    Parameter name.

    type

    Parameter type.

  • Add item to the end of this list.

    Declaration

    Swift

    open func append(_ item: Parameter)

    Parameters

    item

    Item to be added.

  • Add all the items of list to the end of this list.

    Declaration

    Swift

    open func append(contentsOf list: ParameterList)

    Parameters

    list

    Items to be added.

  • Declaration

    Swift

    open func copy() -> ParameterList

    Return Value

    A shallow copy of this list.

  • Declaration

    Swift

    open func filter(_ predicate: @escaping (Parameter) -> Bool) -> ParameterList

    Parameters

    predicate

    Function to be applied to each item of this list. Items matching this predicate will be returned in the new list.

    Return Value

    A new list which contains the items of this list that match a specified predicate function. Ordering is preserved.

  • Throws

    EmptyListException if the list is empty.

    Declaration

    Swift

    open func first() -> Parameter

    Return Value

    The first item in this list.

  • Convert array to list.

    Declaration

    Swift

    open class func fromArray(_ array: Array<Parameter>) -> ParameterList

    Parameters

    array

    Array with source items.

    Return Value

    New list with items copied from array parameter.

  • Declaration

    Swift

    open func includes(item: Parameter) -> Bool

    Parameters

    item

    Item for comparison. Comparison uses the equality property, which would usually be expected to match the == operator for item type Parameter.

    Return Value

    true if this list contains item.

  • Declaration

    Swift

    open func indexOf(item: Parameter, start: Int = (0 as Int)) -> Int

    Parameters

    item

    Item for comparison. Comparison uses the equality property, which would usually be expected to match the == operator for item type Parameter.

    start

    Zero-based starting index (search moves forwards from this index).

    Return Value

    First index in this list of item, or -1 if not found.

  • Insert item into this list, before the item (if any) at index.

    Throws

    ListIndexException if index is out of range (0 to length).

    Declaration

    Swift

    open func insert(at index: Int, item: Parameter)

    Parameters

    index

    Zero-based index.

    item

    Item to be added.

  • Insert all items of list into this list, before the item (if any) at index.

    Throws

    ListIndexException if index is out of range (0 to length).

    Declaration

    Swift

    open func insert(at index: Int, contentsOf list: ParameterList)

    Parameters

    index

    Zero-based index.

    list

    List of items to be inserted.

  • Throws

    ListIndexException if index is out of range (0 to length - 1).

    Declaration

    Swift

    open func item(at index: Int) -> Parameter

    Parameters

    index

    Zero-based index.

    Return Value

    The item in this list at the specified index.

  • Throws

    EmptyListException if the list is empty.

    Declaration

    Swift

    open func last() -> Parameter

    Return Value

    The last item in this list.

  • Declaration

    Swift

    open func lastIndexOf(item: Parameter, start: Int = (2147483647 as Int)) -> Int

    Parameters

    item

    Item for comparison. Comparison uses the equality property, which would usually be expected to match the == operator for item type Parameter.

    start

    Zero-based starting index (search moves backwards from this index).

    Return Value

    Last index in this list of item, or -1 if not found.

  • Declaration

    Swift

    open func makeIterator() -> IndexingIterator<Array<Parameter>>

    Return Value

    This list converted to a Swift iterator.

  • Removed the parameter with the specified name.

    open func remove(name: String) -> Bool

    Parameters

    name

    Return Value

    true if a parameter with the specified name was found (and removed), otherwise false.

  • Declaration

    Swift

    open func required(name: String) -> DataValue?

    Parameters

    name

    Required parameter name.

    Return Value

    the value of a required parameter, or throw DataServiceException with status 400 (Client Error) if the parameter is missing.

  • Declaration

    Swift

    open func requiredList(name: String) -> ListBase

    Parameters

    name

    Required parameter name.

    Return Value

    the value of a required parameter with list type, or throw DataServiceException with status 400 (Client Error) if the parameter is missing.

  • Return a new ParameterList that shares the ListBase.untypedList as the list parameter. To ensure type safety, items in list that do not have the item type Parameter will be removed.

    Declaration

    Swift

    open class func share(_ list: ListBase) -> ParameterList

    Parameters

    list

    List whose items will be shared by the resulting list.

    Return Value

    Swift

    open func single() -> Parameter

    Return Value

    A single item from this list.
