枚举 ExecutionState

java.lang.Object

java.lang.Enum<ExecutionState>

org.apache.seatunnel.engine.server.execution.ExecutionState

所有已实现的接口:

Serializable, Comparable<ExecutionState>, java.lang.constant.Constable

public enum ExecutionState
extends Enum<ExecutionState>
implements Serializable

An enumeration of all states that a task can be in during its execution. Tasks usually start in the state CREATED and switch states according to this diagram:

 INITIALIZING -> CREATED  -> SCHEDULED -> DEPLOYING  -> RUNNING -> FINISHED
                   |            |          |              |
                   |            |    +-----+--------------+
                   |            V    V
                   |         CANCELLING -----+----> CANCELED
                   |                         |
                   +-------------------------+

                                        ... -> FAILED

 

It is possible to enter the RECONCILING state from CREATED state if job manager fail over, and the RECONCILING state can switch into any existing task state.

It is possible to enter the FAILED state from any other state.

The states FINISHED, CANCELED, and FAILED are considered terminal states.

枚举常量概要

枚举常量

枚举常量	说明
CANCELED
CANCELING
CREATED
DEPLOYING
FAILED
FAILING
FINISHED	This state marks "successfully completed".
INITIALIZING	Restoring last possible valid state of the task if it has it.
RUNNING

方法概要

修饰符和类型	方法	说明
boolean	isEndState()
static ExecutionState	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static ExecutionState[]	values()	按照声明该枚举类型的常量的顺序, 返回一个包含这些常量的数组。

枚举常量详细资料

CREATED

public static final ExecutionState CREATED

DEPLOYING

public static final ExecutionState DEPLOYING

RUNNING

public static final ExecutionState RUNNING

FINISHED

public static final ExecutionState FINISHED

This state marks "successfully completed". It can only be reached when a program reaches the "end of its input". The "end of input" can be reached when consuming a bounded input (fix set of files, bounded query, etc) or when stopping a program (not cancelling!) which make the input look like it reached its end at a specific point.

CANCELING

public static final ExecutionState CANCELING

CANCELED

public static final ExecutionState CANCELED

FAILING

public static final ExecutionState FAILING

FAILED

public static final ExecutionState FAILED

INITIALIZING

public static final ExecutionState INITIALIZING

Restoring last possible valid state of the task if it has it.

方法详细资料

values

public static ExecutionState[] values()

按照声明该枚举类型的常量的顺序, 返回一个包含这些常量的数组。

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static ExecutionState valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

isEndState

public boolean isEndState()
