SetBase

open class SetBase : DataValue

Base class for strongly-typed sets.

  • The number of items in this set.

    Declaration

    Swift

    public final var count: Int { get }

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

    Declaration

    Swift

    public init(capacity: Int)

    Parameters

    capacity

    Initial capacity.

  • The data type for this list.

    Declaration

    Swift

    override open var dataType: DataType { get }

  • true if this set is empty.

    Declaration

    Swift

    @inline(__always)
public final var isEmpty: Bool { get }

  • true if this set is mutable.

    Declaration

    Swift

    @inline(__always)
public final var isMutable: Bool { get }

  • true if this set is not empty.

    Declaration

    Swift

    @inline(__always)
public final var isNotEmpty: Bool { get }

  • Mark this set as immutable. Subsequent attempts to mutate the set will throw an ImmutableException.

    Declaration

    Swift

    open func makeImmutable()

  • Remove all values from this set.

    Declaration

    Swift

    open func removeAll()

  • The number of values in this set.

    Declaration

    Swift

    @inline(__always)
public final var size: Int { get }

  • Convert this data value to a string. If the dataType is defined by XML Schema Part 2: Datatypes, then the corresponding lexical format is used. JSON format is used for structured values (arrays and objects).

    Declaration

    Swift

    override open func toString() -> String

    Return Value

    Lexical representation of this data value.

  • The underlying untyped set. Use with care, avoiding the addition of objects with an incorrect value type.

    Declaration

    Swift

    @inline(__always)
public final var untypedSet: UntypedSet { get }
