public WorkEvent(Object source, int type, Work work, WorkException exc)
构造方法。

source	最初发生事件的对象。
type	事件类型。
work	发生事件的 Work 对象。
exc	处理 Work 时发生的异常。

英文文档：

WorkEvent

public WorkEvent(Object source,
                 int type,
                 Work work,
                 WorkException exc)

Constructor.

Parameters:

source - The object on which the event initially occurred.

type - The event type.

work - The Work object on which the event occured.

exc - The exception that occured during Work processing.

public WorkEvent(Object source, int type, Work work, WorkException exc, long startDuration)
构造方法。

source	最初发生事件的对象。
type	事件类型。
work	发生事件的 Work 对象。
exc	处理 Work 时发生的异常。
startDuration	开始延迟期限（以毫秒为单位）。

英文文档：

WorkEvent

public WorkEvent(Object source,
                 int type,
                 Work work,
                 WorkException exc,
                 long startDuration)

Constructor.

Parameters:

source - The object on which the event initially occurred.

type - The event type.

work - The Work object on which the event occured.

exc - The exception that occured during Work processing.

startDuration - The start delay duration (in milliseconds).

public int getType()
返回此事件的类型。

return

事件类型。

英文文档：

getType

public int getType()

Return the type of this event.

Returns:

the event type.

public Work getWork()
返回作为事件原因的 Work 实例。

return

Work 实例。

英文文档：

getWork

public Work getWork()

Return the Work instance which is the cause of the event.

Returns:

the Work instance.

public long getStartDuration()
返回开始时间间隔期限。

return

从接受 Work 开始直到开始执行 Work 所经过的时间（以毫秒为单位）。注意，此方法不提供实时保证。如果实际开始时间间隔期限未知，则返回 -1 是有效的。

英文文档：

getStartDuration

public long getStartDuration()

Return the start interval duration.

Returns:

the time elapsed (in milliseconds) since the Work was accepted, until the Work execution started. Note, this does not offer real-time guarantees. It is valid to return -1, if the actual start interval duration is unknown.

public WorkException getException()
返回 WorkException。根据事件类型返回的实际 WorkException 子类型。

return

WorkRejectedException 或 WorkCompletedException（如果有）。

英文文档：

getException

public WorkException getException()

Return the WorkException. The actual WorkException subtype returned depends on the type of the event.

Returns:

a WorkRejectedException or a WorkCompletedException, if any.
