枚举常量概要

枚举常量
枚举常量和说明
`JDK` JDK's default implementation.
`OPENSSL` OpenSSL-based implementation.
`OPENSSL_REFCNT` OpenSSL-based implementation which does not have finalizers and instead implements `ReferenceCounted`.

方法概要

All Methods Static Methods Concrete Methods
限定符和类型	方法和说明
`static boolean`	`isAlpnSupported(SslProvider provider)` Returns `true` if the specified `SslProvider` supports TLS ALPN Extension, `false` otherwise.
`static boolean`	`isOptionSupported(SslProvider sslProvider, SslContextOption<?> option)` Returns `true` if the specified `SslProvider` supports the specified `SslContextOption`, `false` otherwise.
`static boolean`	`isTlsv13Supported(SslProvider sslProvider)` Returns `true` if the specified `SslProvider` supports TLS 1.3, `false` otherwise.
`static boolean`	`isTlsv13Supported(SslProvider sslProvider, java.security.Provider provider)` Returns `true` if the specified `SslProvider` supports TLS 1.3, `false` otherwise.
`static SslProvider`	`valueOf(java.lang.String name)` 返回带有指定名称的该类型的枚举常量。
`static SslProvider[]`	`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。

- 方法详细资料
  - values
```
public static SslProvider[] 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 (SslProvider c : SslProvider.values())
    System.out.println(c);
```
    返回:
    
    按照声明该枚举类型的常量的顺序返回的包含这些常量的数组
  - valueOf
```
public static SslProvider 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
    
    java.lang.NullPointerException - 如果参数为空值
  - isAlpnSupported
```
public static boolean isAlpnSupported(SslProvider provider)
```
    Returns true if the specified SslProvider supports TLS ALPN Extension, false otherwise.
  - isTlsv13Supported
```
public static boolean isTlsv13Supported(SslProvider sslProvider)
```
    Returns true if the specified SslProvider supports TLS 1.3, false otherwise.
  - isTlsv13Supported
```
public static boolean isTlsv13Supported(SslProvider sslProvider,
                                        java.security.Provider provider)
```
    Returns true if the specified SslProvider supports TLS 1.3, false otherwise.
  - isOptionSupported
```
public static boolean isOptionSupported(SslProvider sslProvider,
                                        SslContextOption<?> option)
```
    Returns true if the specified SslProvider supports the specified SslContextOption, false otherwise.
