  - values
```
public static CompactRangeOptions.BottommostLevelCompaction[] 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 (CompactRangeOptions.BottommostLevelCompaction c : CompactRangeOptions.BottommostLevelCompaction.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 CompactRangeOptions.BottommostLevelCompaction 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
  - getValue
```
public byte getValue()
```
    Returns the byte value of the enumerations value.
    
    返回:
    
    byte representation
  - fromRocksId
```
public static CompactRangeOptions.BottommostLevelCompaction fromRocksId(int bottommostLevelCompaction)
```
    Returns the BottommostLevelCompaction for the given C++ rocks enum value.
    
    参数:
    
    bottommostLevelCompaction - The value of the BottommostLevelCompaction
    
    返回:
    
    BottommostLevelCompaction instance, or null if none matches
