Enum Constant Detail

• 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.

Method Detail

• values

  public static ErrorState[] 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 (ErrorState c : ErrorState.values())
      System.out.println(c);
  

  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

• isIoAllowed

  public boolean isIoAllowed()

• isConnectionIoAllowed

  public boolean isConnectionIoAllowed()
