枚举常量概要

枚举常量

枚举常量	说明
BLOCK_CIPHER	Symmetric primitive: block cipher
KEY_AGREEMENT	Asymmetric primitive: key agreement and key distribution
KEY_ENCAPSULATION	Asymmetric primitive: key encapsulation mechanism
KEY_WRAP	Symmetric primitive: key wrap
MAC	Symmetric primitive: message authentication code
MESSAGE_DIGEST	Hash function
PUBLIC_KEY_ENCRYPTION	Asymmetric primitive: public key encryption
SECURE_RANDOM	Cryptographic random number generator
SIGNATURE	Asymmetric primitive: signature scheme
STREAM_CIPHER	Symmetric primitive: stream cipher

方法概要

限定符和类型	方法	说明
static CryptoPrimitive	valueOf(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。)
static CryptoPrimitive[]	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 (CryptoPrimitive c : CryptoPrimitive.values()) System.out.println(c);

从类继承的方法 java.lang.Enum

clone, compareTo, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf

从类继承的方法 java.lang.Object

values

public static CryptoPrimitive[] 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 (CryptoPrimitive c : CryptoPrimitive.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 CryptoPrimitive valueOf(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:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
