public WindowImpl(List<T> tuples,
 List<T> newTuples,
 List<T> expiredTuples,
 Long startTimestamp,
 Long endTimestamp)

方法详细资料

get

public List<T> get()

从接口复制的说明: Window

Gets the list of events in the window.

Note: If the number of tuples in windows is huge, invoking get would load all the tuples into memory and may throw an OOM exception. Use windowing with persistence

指定者:

get 在接口中 Window<T>

返回:

the list of events in the window.

getNew

public List<T> getNew()

从接口复制的说明: Window

Get the list of newly added events in the window since the last time the window was generated.

指定者:

getNew 在接口中 Window<T>

返回:

the list of newly added events in the window.

getExpired

public List<T> getExpired()

从接口复制的说明: Window

Get the list of events expired from the window since the last time the window was generated.

指定者:

getExpired 在接口中 Window<T>

返回:

the list of events expired from the window.

getStartTimestamp

public Long getStartTimestamp()

从接口复制的说明: Window

Returns the window start timestamp. Will return null if the window length is not based on time duration.

指定者:

getStartTimestamp 在接口中 Window<T>

返回:

the window start timestamp or null if the window length is not time based

getEndTimestamp

public Long getEndTimestamp()

从接口复制的说明: Window

If processing based on event time, returns the window end time based on watermark otherwise returns the window end time based on processing time.

指定者:

getEndTimestamp 在接口中 Window<T>

返回:

the window end timestamp
