枚举 BatchExecOverAggregateBase.OverWindowMode

java.lang.Object

java.lang.Enum<BatchExecOverAggregateBase.OverWindowMode>

org.apache.flink.table.planner.plan.nodes.exec.batch.BatchExecOverAggregateBase.OverWindowMode

所有已实现的接口:

Serializable, Comparable<BatchExecOverAggregateBase.OverWindowMode>

封闭类:

BatchExecOverAggregateBase

public static enum BatchExecOverAggregateBase.OverWindowMode
extends Enum<BatchExecOverAggregateBase.OverWindowMode>

OverWindowMode describes the mode of a group in over window.

枚举常量概要

枚举常量

枚举常量和说明
INSENSITIVE The INSENSITIVE mode does not care the window framing without LEAD/LAG agg function, for example RANK/DENSE_RANK/PERCENT_RANK/CUME_DIST/ROW_NUMBER.
OFFSET The OFFSET mode does not care the window framing with LEAD/LAG agg function, see SqlLeadLagAggFunction.
RANGE The RANGE mode allows window framing with RANGE clause.
ROW The ROW mode allows window framing with ROW clause.

方法详细资料

values

public static BatchExecOverAggregateBase.OverWindowMode[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (BatchExecOverAggregateBase.OverWindowMode c : BatchExecOverAggregateBase.OverWindowMode.values())
    System.out.println(c);

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 BatchExecOverAggregateBase.OverWindowMode 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
