public static java.lang.String toString(java.util.Set<PosixFilePermission> perms)
String
representation of a set of permissions.
If the set contains null
or elements that are not of type
PosixFilePermission
then these elements are ignored.
perms
- The set of permissions
fromString(java.lang.String)
public static java.util.Set<PosixFilePermission> fromString(java.lang.String perms)
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---");
