Enum Constant Detail

• FATAL_ALERT

  public static final ApplicationProtocolConfig.SelectorFailureBehavior FATAL_ALERT

  If the peer who selects the application protocol doesn't find a match this will result in the failing the handshake with a fatal alert.

  For example in the case of ALPN this will result in a no_application_protocol(120) alert.

• NO_ADVERTISE

  public static final ApplicationProtocolConfig.SelectorFailureBehavior NO_ADVERTISE

  If the peer who selects the application protocol doesn't find a match it will pretend no to support the TLS extension by not advertising support for the TLS extension in the handshake. This is used in cases where a "best effort" is desired to talk even if there is no matching protocol.

• CHOOSE_MY_LAST_PROTOCOL

  public static final ApplicationProtocolConfig.SelectorFailureBehavior CHOOSE_MY_LAST_PROTOCOL

  If the peer who selects the application protocol doesn't find a match it will just select the last protocol it advertised support for. This is used in cases where a "best effort" is desired to talk even if there is no matching protocol, and the assumption is the "most general" fallback protocol is typically listed last.

  This may be illegal for some RFCs but was observed behavior by some SSL implementations, and is supported for flexibility/compatibility.

Method Detail

• values

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

  Returns:

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

• valueOf

  public static ApplicationProtocolConfig.SelectorFailureBehavior 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
