Class Literal

Literal constant (e.g., 1 or "hello").

Syntax
public class Literal : Expression<Literal, Table>, IVisitable<IExpressionVisitor>, ICloneable<Literal, Table, Expression>, ICloneable<Expression>, IDirectedAcyclicGraph<Expression>
Remarks

The special value Null means the null value on any underlying platform, which generally has a platform-specific representation. Emitters that target platforms that represent null with some string other than "null" need to handle this case explicitly.
