Argument

public sealed class Argument

One argument within a bracketed list, i.e. the "y: 5" in "point(1, y: 5)".

Properties

At

public Fragment At { get; }

Gets the fragment to blame when this argument is at fault. That is the name when there is one, so that a complaint about an unknown argument underlines the name rather than the value behind it.

IsEmpty

public bool IsEmpty { get; }

Gets whether this argument has no value at all, as the middle one in "rgb(1,,3)" does.

IsNamed

public bool IsNamed { get; }

Gets whether this argument was given by name rather than by position.

Name

public string Name { get; }

Gets the name of this argument, or null when it was given by position.

Value

public Fragments Value { get; }

Gets the value of this argument, ready to be handed to an interpreter.

Methods

Matches

public bool Matches(params string[] names)

Test whether this argument was given under one of these names.

Useful when the alias changes the meaning rather than merely the spelling, as "d: 10" and "r: 10" do on a circle.

Parameters:

names (params string[])

Names to test against.

ToString

public override string ToString()

Overrides: Object.ToString
