BOOKKEEPER_FIRST

public static final OffloadedReadPriority BOOKKEEPER_FIRST

For offloaded messages, readers will try to read from bookkeeper at first, if messages not exist at bookkeeper then read from offloaded storage.

TIERED_STORAGE_FIRST

public static final OffloadedReadPriority TIERED_STORAGE_FIRST

For offloaded messages, readers will try to read from offloaded storage first, even they are still exist in bookkeeper.

方法详细资料

values

public static OffloadedReadPriority[] 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 (OffloadedReadPriority c : OffloadedReadPriority.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 OffloadedReadPriority valueOf(java.lang.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:

java.lang.IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

java.lang.NullPointerException - 如果参数为空值

equalsName

public boolean equalsName(java.lang.String otherName)

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Enum<OffloadedReadPriority>

fromString

public static OffloadedReadPriority fromString(java.lang.String str)

getValue

public java.lang.String getValue()
