构造器详细信息

WorkEvent

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

Constructor.

参数:: 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.

WorkEvent

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

Constructor.

参数:: 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).

方法详细信息

getType

public int getType()

Return the type of this event.

返回:: the event type.

getWork

public Work getWork()

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

返回:: the Work instance.

getStartDuration

public long getStartDuration()

Return the start interval duration.

返回:: 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.

getException

public WorkException getException()

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

返回:: a WorkRejectedException or a WorkCompletedException, if any.
