枚举常量详细资料

NO

public static final FileLockMethod NO

This locking method means no locking is used at all.

FILE

public static final FileLockMethod FILE

This locking method means the cooperative file locking protocol should be used.

SOCKET

public static final FileLockMethod SOCKET

This locking method means a socket is created on the given machine.

FS

public static final FileLockMethod FS

方法详细资料

values

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