枚举 PosixFilePermission

java.lang.Object

java.lang.Enum<PosixFilePermission>

java.nio.file.attribute.PosixFilePermission

所有已实现的接口:

Serializable, Comparable<PosixFilePermission>

public enum PosixFilePermission
extends Enum<PosixFilePermission>

Defines the bits for use with the PosixFileAttributes#permissions() attribute.

The PosixFilePermissions class defines methods for manipulating set of permissions.

从以下版本开始:

1.7

枚举常量概要

枚举常量

枚举常量	说明
GROUP_EXECUTE	Execute/search permission, group.
GROUP_READ	Read permission, group.
GROUP_WRITE	Write permission, group.
OTHERS_EXECUTE	Execute/search permission, others.
OTHERS_READ	Read permission, others.
OTHERS_WRITE	Write permission, others.
OWNER_EXECUTE	Execute/search permission, owner.
OWNER_READ	Read permission, owner.
OWNER_WRITE	Write permission, owner.

方法概要

限定符和类型	方法	说明
static PosixFilePermission	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。)
static PosixFilePermission[]	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 (PosixFilePermission c : PosixFilePermission.values()) System.out.println(c);

方法详细资料

values

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