枚举 SplitTransaction.SplitTransactionPhase

java.lang.Object

java.lang.Enum<SplitTransaction.SplitTransactionPhase>

org.apache.hadoop.hbase.regionserver.SplitTransaction.SplitTransactionPhase

所有已实现的接口:

Serializable, Comparable<SplitTransaction.SplitTransactionPhase>

封闭接口:

SplitTransaction

public static enum SplitTransaction.SplitTransactionPhase
extends Enum<SplitTransaction.SplitTransactionPhase>

Each enum is a step in the split transaction.

STARTED

public static final SplitTransaction.SplitTransactionPhase STARTED

Started

PREPARED

public static final SplitTransaction.SplitTransactionPhase PREPARED

Prepared

public static final SplitTransaction.SplitTransactionPhase BEFORE_PRE_SPLIT_HOOK

Before preSplit coprocessor hook

AFTER_PRE_SPLIT_HOOK

public static final SplitTransaction.SplitTransactionPhase AFTER_PRE_SPLIT_HOOK

After preSplit coprocessor hook

SET_SPLITTING

public static final SplitTransaction.SplitTransactionPhase SET_SPLITTING

Set region as in transition, set it into SPLITTING state.

CREATE_SPLIT_DIR

public static final SplitTransaction.SplitTransactionPhase CREATE_SPLIT_DIR

We created the temporary split data directory.

CLOSED_PARENT_REGION

public static final SplitTransaction.SplitTransactionPhase CLOSED_PARENT_REGION

Closed the parent region.

OFFLINED_PARENT

public static final SplitTransaction.SplitTransactionPhase OFFLINED_PARENT

The parent has been taken out of the server's online regions list.

STARTED_REGION_A_CREATION

public static final SplitTransaction.SplitTransactionPhase STARTED_REGION_A_CREATION

Started in on creation of the first daughter region.

STARTED_REGION_B_CREATION

public static final SplitTransaction.SplitTransactionPhase STARTED_REGION_B_CREATION

方法详细资料

values

public static SplitTransaction.SplitTransactionPhase[] 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 (SplitTransaction.SplitTransactionPhase c : SplitTransaction.SplitTransactionPhase.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 SplitTransaction.SplitTransactionPhase 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
