jdk.nio.file.attribute.PosixFilePermissions
This class consists exclusively of static methods that operate on sets of PosixFilePermission objects.

*as-file-attributeclj
(*as-file-attribute perms)Creates a FileAttribute, encapsulating a copy of the given file permissions, suitable for passing to the createFile or createDirectory methods.
perms - the set of permissions - java.util.Set
returns: an attribute encapsulating the given file permissions with
name "posix:permissions" - java.nio.file.attribute.FileAttribute<java.util.Set<java.nio.file.attribute.PosixFilePermission>>
throws: java.lang.ClassCastException - if the set contains elements that are not of type PosixFilePermission
Creates a FileAttribute, encapsulating a copy of the given file
permissions, suitable for passing to the createFile or createDirectory
methods.
perms - the set of permissions - `java.util.Set`
returns: an attribute encapsulating the given file permissions with
name "posix:permissions" - `java.nio.file.attribute.FileAttribute<java.util.Set<java.nio.file.attribute.PosixFilePermission>>`
throws: java.lang.ClassCastException - if the set contains elements that are not of type PosixFilePermission*from-stringclj
(*from-string perms)Returns the set of permissions corresponding to a given String representation.
The perms parameter is a String representing the permissions. It has 9 characters that are interpreted as three sets of three. The first set refers to the owner's permissions; the next to the group permissions and the last to others. Within each set, the first character is 'r' to indicate permission to read, the second character is 'w' to indicate permission to write, and the third character is 'x' for execute permission. Where a permission is not set then the corresponding character is set to '-'.
Usage Example: Suppose we require the set of permissions that indicate the owner has read, write, and execute permissions, the group has read and execute permissions and others have none.
Set<PosixFilePermission> perms = PosixFilePermissions.fromString("rwxr-x---");
perms - string representing a set of permissions - java.lang.String
returns: the resulting set of permissions - java.util.Set<java.nio.file.attribute.PosixFilePermission>
throws: java.lang.IllegalArgumentException - if the string cannot be converted to a set of permissions
Returns the set of permissions corresponding to a given String
representation.

throws: java.lang.IllegalArgumentException - if the string cannot be converted to a set of permissions*to-stringclj
(*to-string perms)Returns the String representation of a set of permissions. It is guaranteed that the returned String can be parsed by the fromString(java.lang.String) method.
If the set contains null or elements that are not of type PosixFilePermission then these elements are ignored.
