public enum ErrorState extends Enum<ErrorState>

  • Enum Constant Details

    • NONE

      public static final ErrorState NONE
      Not in an error state.

    • CLOSE_CLEAN

      public static final ErrorState CLOSE_CLEAN
      The current request/response is in an error state and while it is safe to complete the current response it is not safe to continue to use the existing connection which must be closed once the response has been completed. For multiplexed protocols, the channel must be closed when the current request/response completes but the connection may continue.

    • CLOSE_NOW

      public static final ErrorState CLOSE_NOW
      The current request/response is in an error state and it is not safe to continue to use them. For multiplexed protocols (such as HTTP/2) the stream/channel must be closed immediately but the connection may continue. For non-multiplexed protocols (AJP, HTTP/1.x) the current connection must be closed.

    • CLOSE_CONNECTION_NOW

      public static final ErrorState CLOSE_CONNECTION_NOW
      An error has been detected that impacts the underlying network connection. It is not safe to continue using the network connection which must be closed immediately. For multiplexed protocols (such as HTTP/2) this impacts all multiplexed channels.

    • values

      public static ErrorState[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static ErrorState 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

    • isError

      public boolean isError()

    • getMostSevere

      public ErrorState getMostSevere(ErrorState input)
      Compare this ErrorState with the provided ErrorState and return the most severe.
      Parameters:
      input - The error state to compare to this one
      Returns:
      The most severe error state from the the provided error state and this one
