Enum Class PooledObjectState

java.lang.Object
java.lang.Enum<PooledObjectState>
cloud.opencode.base.pool.factory.PooledObjectState
All Implemented Interfaces:
Serializable, Comparable<PooledObjectState>, Constable
public enum PooledObjectState extends Enum<PooledObjectState>
PooledObjectState - Pooled Object State Enumeration PooledObjectState - 池化对象状态枚举

Defines the lifecycle states of a pooled object.

定义池化对象的生命周期状态。

State Transitions | 状态转换:

IDLE -> ALLOCATED (borrow)
ALLOCATED -> RETURNING -> IDLE (return)
IDLE -> EVICTION -> INVALID (evict)
ALLOCATED -> INVALID (invalidate)
Any -> ABANDONED (timeout detection)

Features | 主要功能:

  • State tracking for pooled objects - 池化对象状态追踪
  • Thread-safe state transitions - 线程安全的状态转换
  • Lifecycle management support - 生命周期管理支持

Usage Examples | 使用示例:

PooledObjectState state = pooledObject.getState();
if (state == PooledObjectState.IDLE) {
    // Object available for borrowing
}
Since:
JDK 25, opencode-base-pool V1.0.0

    • valueOf

      public static PooledObjectState 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
