All Implemented Interfaces:

Serializable

public class InvalidSyntaxException
extends Exception

Exception thrown when token parsing encounters unexpected content.

This exception is thrown by the tokenizer when expectations fail, such as:

• Tokenizer.expectAndConsumeNextStringToken(String) - when the next token doesn't match the expected value
• Tokenizer.expectAndConsumeNextTerminatorToken(Terminator) - when the next token was matched by a different terminator
• Tokenizer.peekExpectNoneOf(String...) - when the next token matches a forbidden value

Example handling:

 try {
     tokenizer.expectAndConsumeNextStringToken("if");
     // Parse if statement...
 } catch (InvalidSyntaxException e) {
     System.err.println("Syntax error: " + e.getMessage());
     // Error recovery or abort
 }
 

The exception message describes what was expected and what was actually encountered, useful for error reporting to users.
