Enum StateMachine

java.lang.Object

java.lang.Enum<StateMachine>

org.aoju.bus.socket.origin.StateMachine

All Implemented Interfaces:

Serializable, Comparable<StateMachine>

public enum StateMachine
extends Enum<StateMachine>

列举了当前所关注的各类状态枚举

当前枚举的各状态机事件在发生后都会及时触发Message.stateEvent(AioSession, StateMachine, Throwable)方法 因此用户在实现的Message接口中可对自己关心的状态机事件进行处理

Since:

JDK 1.8+

Enum Constant Summary

Enum Constants

Enum Constant and Description
DECODE_EXCEPTION 协议解码异常 执行Protocol.decode(ByteBuffer, AioSession)期间发生未捕获的异常
INPUT_EXCEPTION 读操作异常 在底层服务执行read操作期间因发生异常情况出发了CompletionHandler.failed(Throwable, Object) 未来该状态机可能会废除,并转移至NetMonitor
INPUT_SHUTDOWN 读通道已被关闭 通常由以下几种情况会触发该状态： 对端主动关闭write通道,致使本通常满足了EOF条件 当前AioSession处理完读操作后检测到自身正处于SESSION_CLOSING状态 未来该状态机可能会废除,并转移至NetMonitor
NEW_SESSION 连接已建立并构建Session对象
OUTPUT_EXCEPTION 写操作异常 在底层服务执行write操作期间因发生异常情况出发了CompletionHandler.failed(Throwable, Object) 未来该状态机可能会废除,并转移至NetMonitor
PROCESS_EXCEPTION 业务处理异常 执行Message.process(AioSession, Object)期间发生用户未捕获的异常
REJECT_ACCEPT 拒绝接受连接,仅Server端有效
SESSION_CLOSED 会话关闭成功 AioSession关闭成功
SESSION_CLOSING 会话正在关闭中 执行了AioSession.close(boolean)方法,并且当前还存在待输出的数据

Enum Constant Detail

NEW_SESSION

public static final StateMachine NEW_SESSION

连接已建立并构建Session对象

INPUT_SHUTDOWN

public static final StateMachine INPUT_SHUTDOWN

读通道已被关闭 通常由以下几种情况会触发该状态：

1. 对端主动关闭write通道,致使本通常满足了EOF条件
2. 当前AioSession处理完读操作后检测到自身正处于SESSION_CLOSING状态

未来该状态机可能会废除,并转移至NetMonitor

PROCESS_EXCEPTION

public static final StateMachine PROCESS_EXCEPTION

业务处理异常 执行Message.process(AioSession, Object)期间发生用户未捕获的异常

DECODE_EXCEPTION

public static final StateMachine DECODE_EXCEPTION

协议解码异常 执行Protocol.decode(ByteBuffer, AioSession)期间发生未捕获的异常

INPUT_EXCEPTION

public static final StateMachine INPUT_EXCEPTION

读操作异常 在底层服务执行read操作期间因发生异常情况出发了CompletionHandler.failed(Throwable, Object) 未来该状态机可能会废除,并转移至NetMonitor

OUTPUT_EXCEPTION

public static final StateMachine OUTPUT_EXCEPTION

写操作异常 在底层服务执行write操作期间因发生异常情况出发了CompletionHandler.failed(Throwable, Object) 未来该状态机可能会废除,并转移至NetMonitor

SESSION_CLOSING

public static final StateMachine SESSION_CLOSING

会话正在关闭中 执行了AioSession.close(boolean)方法,并且当前还存在待输出的数据

SESSION_CLOSED

public static final StateMachine SESSION_CLOSED

会话关闭成功 AioSession关闭成功

REJECT_ACCEPT

public static final StateMachine REJECT_ACCEPT

拒绝接受连接,仅Server端有效

Method Detail

values

public static StateMachine[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (StateMachine c : StateMachine.values())
    System.out.println(c);

Returns:

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

valueOf

public static StateMachine valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null
