Interface Ast

All Known Implementing Classes:
Ast.DefaultAst
public interface Ast
Interface to generate abstract syntax tree from tokens. Generic language parser usually contains lexing and parsing where this Ast represents the latter parsing side. Parsing looks tokens and combines those together into nodes and we get closer to understand commands, its options and arguments whether those belong to command or option. Parser don't look if for example option arguments makes sense which happen later when ast tree is visited.
