    - #### ALLOW

          public static final AclEntryType ALLOW

      Explicitly grants access to a file or directory.

    - #### DENY

          public static final AclEntryType DENY

      Explicitly denies access to a file or directory.

    - #### AUDIT

          public static final AclEntryType AUDIT

      Log, in a system dependent way, the access specified in the permissions component of the ACL entry.

    - #### ALARM

          public static final AclEntryType ALARM

      Generate an alarm, in a system dependent way, the access specified in the permissions component of the ACL entry.

  - ### Method Detail

    - #### values

          public static AclEntryType[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (AclEntryType c : AclEntryType.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static AclEntryType valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
