class Expression : IExpression(source)

Constructors

constructor(tree: ITree)

This constructor does not do any parsing, and thus is much faster than the other one.

constructor(n: ITreeNode<out Any>)

constructor(s: String)

This constructor parses the String into an Expression.

Properties

val rootNode: ITreeNode<out Any>
