public class OpenExpressionException extends OpenException
Expression Exception 表达式异常

Base exception for all expression-related errors including parsing, evaluation, type conversion, and security violations.

所有表达式相关错误的基础异常，包括解析、求值、类型转换和安全违规。

Features | 主要功能:

  • Rich error context with expression string and position - 丰富的错误上下文，包含表达式字符串和位置
  • Static factory methods for common error types - 常见错误类型的静态工厂方法
  • Supports parse, evaluation, type, property, method, and security errors - 支持解析、求值、类型、属性、方法和安全错误

Usage Examples | 使用示例:

// Catch expression errors
try {
    OpenExpression.eval("invalid ++ expr");
} catch (OpenExpressionException e) {
    String expr = e.getExpression();
    int pos = e.getPosition();
}

// Create specific error types
throw OpenExpressionException.parseError("Unexpected token", "1 ++ 2", 2);
throw OpenExpressionException.divisionByZero();

Security | 安全性:

  • Thread-safe: Yes, immutable after construction - 线程安全: 是，构造后不可变
  • Null-safe: Yes, null expression/position handled - 空值安全: 是，null表达式/位置已处理
Since:
JDK 25, opencode-base-expression V1.0.0
