枚举 ScannerContext.LimitScope

java.lang.Object

java.lang.Enum<ScannerContext.LimitScope>

org.apache.hadoop.hbase.regionserver.ScannerContext.LimitScope

所有已实现的接口:

Serializable, Comparable<ScannerContext.LimitScope>

封闭类:

ScannerContext

public static enum ScannerContext.LimitScope
extends Enum<ScannerContext.LimitScope>

The various scopes where a limit can be enforced. Used to differentiate when a limit should be enforced or not.

枚举常量概要

枚举常量

枚举常量和说明
BETWEEN_CELLS Enforcing a limit between cells means that the limit will be considered after each full cell has been retrieved
BETWEEN_ROWS Enforcing a limit between rows means that the limit will not be considered until all the cells for a particular row have been retrieved

方法概要

限定符和类型	方法和说明
static ScannerContext.LimitScope	valueOf(String name) 返回带有指定名称的该类型的枚举常量。
static ScannerContext.LimitScope[]	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。

枚举常量详细资料

BETWEEN_ROWS

public static final ScannerContext.LimitScope BETWEEN_ROWS

Enforcing a limit between rows means that the limit will not be considered until all the cells for a particular row have been retrieved

BETWEEN_CELLS

public static final ScannerContext.LimitScope BETWEEN_CELLS

Enforcing a limit between cells means that the limit will be considered after each full cell has been retrieved

方法详细资料

values

public static ScannerContext.LimitScope[] 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 (ScannerContext.LimitScope c : ScannerContext.LimitScope.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 ScannerContext.LimitScope 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
