枚举 KeyValue.Type

java.lang.Object

java.lang.Enum<KeyValue.Type>

org.apache.hadoop.hbase.KeyValue.Type

所有已实现的接口:

Serializable, Comparable<KeyValue.Type>

封闭类:

KeyValue

public static enum KeyValue.Type
extends Enum<KeyValue.Type>

Key type. Has space for other key types to be added later. Cannot rely on enum ordinals . They change if item is removed or moved. Do our own codes.

枚举常量详细资料

Minimum

public static final KeyValue.Type Minimum

Put

public static final KeyValue.Type Put

Delete

public static final KeyValue.Type Delete

DeleteFamilyVersion

public static final KeyValue.Type DeleteFamilyVersion

DeleteColumn

方法详细资料

values

public static KeyValue.Type[] 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 (KeyValue.Type c : KeyValue.Type.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 KeyValue.Type 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

getCode

public byte getCode()

codeToType

public static KeyValue.Type codeToType(byte b)

Cannot rely on enum ordinals . They change if item is removed or moved. Do our own codes.

参数:

b -

返回:

Type associated with passed code.
