枚举 Base64Dialect

java.lang.Object

java.lang.Enum<Base64Dialect>

io.netty.handler.codec.base64.Base64Dialect

所有已实现的接口:

java.io.Serializable, java.lang.Comparable<Base64Dialect>

public enum Base64Dialect
extends java.lang.Enum<Base64Dialect>

Enumeration of supported Base64 dialects.

The internal lookup tables in this class has been derived from Robert Harder's Public Domain Base64 Encoder/Decoder.

枚举常量详细资料

STANDARD

public static final Base64Dialect STANDARD

Standard Base64 encoding as described in the Section 3 of RFC3548.

URL_SAFE

public static final Base64Dialect URL_SAFE

Base64-like encoding that is URL-safe as described in the Section 4 of RFC3548. It is important to note that data encoded this way is not officially valid Base64, or at the very least should not be called Base64 without also specifying that is was encoded using the URL-safe dialect.

ORDERED

public static final Base64Dialect ORDERED

Special "ordered" dialect of Base64 described in RFC1940.

方法详细资料

values

public static Base64Dialect[] 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 (Base64Dialect c : Base64Dialect.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 Base64Dialect 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
