public struct Args : RandomAccessCollection

Arguments passed to a subroutine.

  • Fetches the argument at the specified position.

    Throws

    If the argument not exists, is undefined or not convertible to the desired type.

    Complexity

    O(1).

    Declaration

    Swift

    public func get<T : PerlScalarConvertible>(_ index: Int) throws -> T

    Parameters

    index

    The position of the argument to fetch.

  • Fetches the argument at the specified position.

    Throws

    If the argument is not convertible to the desired type.

    Complexity

    O(1).

    Declaration

    Swift

    public func get<T : PerlScalarConvertible>(_ index: Int) throws -> T?

    Parameters

    index

  • The position of the first argument.

    If the arguments are empty, startIndex is equal to endIndex.

    Declaration

    Swift

    public var startIndex: Int

  • The arguments’ past the end position—that is, the position one greater than the last valid subscript argument.

    If the arguments are empty, endIndex is equal to startIndex.

    Declaration

    Swift

    public var endIndex: Int

  • Accesses the argument at the specified position.

    Complexity

    O(1).

    Declaration

    Swift

    public subscript(index: Int) -> PerlScalar

    Parameters

    index
