Enum Session.Validation

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Session.Validation>
    Enclosing interface:
    Session
    public static enum Session.Validation
extends java.lang.Enum<Session.Validation>
    Specifiers for how much effort to put into validating a Session. The amount of effort put into checking should be non-decreasing from NONE (least effort) to COMPLETE (most effort). Exactly what is checked is implementation dependent. For example, a memory resident database driver might implement SOCKET and NETWORK to be the same as LOCAL. SERVER might verify that a database manager thread is running and COMPLETE might trigger the database manager thread to run a deadlock detection algorithm.

    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      COMPLETE
      everything that can be checked is working.
      LOCAL
      NONE plus check local resources
      NETWORK
      SOCKET plus the network is intact (network PING)
      NONE
      isValid fails only if the Session is closed.
      SERVER
      NETWORK plus significant server processes are running
      SOCKET
      LOCAL plus the server isn't obviously unreachable (dead socket)

    • Method Detail

      • values

        public static Session.Validation[] 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 (Session.Validation c : Session.Validation.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static Session.Validation valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
