枚举 ApplicationProtocolConfig.SelectorFailureBehavior

java.lang.Object

java.lang.Enum<ApplicationProtocolConfig.SelectorFailureBehavior>

io.netty.handler.ssl.ApplicationProtocolConfig.SelectorFailureBehavior

所有已实现的接口:

java.io.Serializable, java.lang.Comparable<ApplicationProtocolConfig.SelectorFailureBehavior>

封闭类:

ApplicationProtocolConfig

public static enum ApplicationProtocolConfig.SelectorFailureBehavior
extends java.lang.Enum<ApplicationProtocolConfig.SelectorFailureBehavior>

Defines the most common behaviors for the peer that selects the application protocol.

枚举常量概要

枚举常量

枚举常量和说明
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.
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.
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.

枚举常量详细资料

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.

方法详细资料

values

public static ApplicationProtocolConfig.SelectorFailureBehavior[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (ApplicationProtocolConfig.SelectorFailureBehavior c : ApplicationProtocolConfig.SelectorFailureBehavior.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组

valueOf

public static ApplicationProtocolConfig.SelectorFailureBehavior valueOf(java.lang.String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

java.lang.IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量, 则抛出 IllegalArgumentException

java.lang.NullPointerException - 如果参数为空值, 则抛出 NullPointerException
