FALSE Deleted Cells are not retained.
TRUE Deleted Cells are retained until they are removed by other means such TTL or VERSIONS.
TTL Deleted Cells are retained until the delete marker expires due to TTL.

枚举常量详细资料

FALSE

public static final KeepDeletedCells FALSE

Deleted Cells are not retained.

TRUE

public static final KeepDeletedCells TRUE

Deleted Cells are retained until they are removed by other means such TTL or VERSIONS. If no TTL is specified or no new versions of delete cells are written, they are retained forever.

TTL

public static final KeepDeletedCells TTL

Deleted Cells are retained until the delete marker expires due to TTL. This is useful when TTL is combined with MIN_VERSIONS and one wants to keep a minimum number of versions around but at the same time remove deleted cells after the TTL.

方法详细资料

values

public static KeepDeletedCells[] 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 (KeepDeletedCells c : KeepDeletedCells.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 KeepDeletedCells 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

getValue

public static KeepDeletedCells getValue(String val)
