public final class ModifierUtil
extends Object

Modifier Utility Class - Java modifier checking operations 修饰符工具类 - Java 修饰符检查操作

Provides utilities for checking Java modifiers on classes, methods, and fields.

提供类、方法和字段的 Java 修饰符检查工具。

Features | 主要功能:

• Access modifiers (public, private, protected, package) - 访问修饰符
• Class modifiers (abstract, final, interface) - 类修饰符
• Member modifiers (static, final, volatile, transient) - 成员修饰符
• Method modifiers (synchronized, native, strict) - 方法修饰符

Usage Examples | 使用示例:

// Check access modifier - 检查访问修饰符
boolean isPub = ModifierUtil.isPublic(field);

// Check class modifier - 检查类修饰符
boolean isAbstract = ModifierUtil.isAbstract(MyClass.class);

// Get modifier string - 获取修饰符字符串
String modStr = ModifierUtil.toString(method);

Security | 安全性:

• Thread-safe: Yes (stateless) - 线程安全: 是 (无状态)
• Null-safe: No - 空值安全: 否

Performance | 性能特性:

• Time complexity: O(1) per check - 每次检查 O(1)
• Space complexity: O(1) - O(1)

Since:

JDK 25, opencode-base-core V1.0.0
