Interpreter Interpreter Mode Definition: Defines the textual method of the language and establishes an interpreter to explain the sentence in the language.
Interpreter seems not very wide, it describes how a language interpreter is constituted, in practical applications, we may rarely construct a language of literacy. We still come to learn about it:
First create an interface to describe common operations.
Public interface AbstractExpression {void interpret (context context);
Take a look at some global information other than the interpreter.
Public interface context {}
Part of AbstractExpression is divided into two species: end-assignment expressions and non-endache expression:
Public Class TerminalExpression Implements AbstractExpression {Public Void Interpret (CONTEXT CONTEXT) {}
For not a grammar rule nonterminal expressions must: public class NonterminalExpression implements AbstractExpression {private AbstractExpression successor; public void setSuccessor (AbstractExpression successor) {this.successor = successor;} public AbstractExpression getSuccessor () {return successor; } Public void interpret (context context) {}}
