  • toString

    public static String toString(Set<PosixFilePermission> perms)

    Returns theString representation of a set of permissions. It is guaranteed that the returnedString can be parsed by thefromString(java.lang.String) method.

    If the set containsnull or elements that are not of typePosixFilePermission then these elements are ignored.

    Parameters:

    perms - the set of permissions

    Returns:

    the string representation of the permission set

  • fromString

    public static Set<PosixFilePermission> fromString(String perms)

    Returns the set of permissions corresponding to a givenString representation.

    Theperms parameter is aString 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---");

    Parameters:

    perms - string representing a set of permissions

    Returns:

    the resulting set of permissions

    Throws:

    IllegalArgumentException - if the string cannot be converted to a set of permissions
