Enum Class LockType

java.lang.Object
java.lang.Enum<LockType>
cloud.opencode.base.lock.LockType
All Implemented Interfaces:
Serializable, Comparable<LockType>, Constable
public enum LockType extends Enum<LockType>
Lock Type Enumeration 锁类型枚举

Defines the different types of locks available in the lock component.

定义锁组件中可用的不同锁类型。

Features | 主要功能:

  • Type identification for lock configuration - 锁配置的类型标识
  • Factory method selection support - 工厂方法选择支持

Usage Examples | 使用示例:

// Select a lock type for configuration
// 选择锁类型进行配置
LockType type = LockType.REENTRANT;
Lock lock = LockManager.create(type);

Security | 安全性:

  • Thread-safe: Yes (immutable enum) - 线程安全: 是（不可变枚举）
  • Null-safe: Yes - 空值安全: 是
Since:
JDK 25, opencode-base-lock V1.0.0

    Enum Constant
    Description
    READ_WRITE
    Read-write lock - allows concurrent readers, exclusive writers 读写锁 - 允许并发读取，排他写入

      public static LockType[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.

      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static LockType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
