枚举常量详细资料

HEAD

public static final ChainStrategy HEAD

The operator won't be chained with preceding operators, but maybe chained with succeeding operators.

ALWAYS

public static final ChainStrategy ALWAYS

Operators will be chained together when possible.

NEVER

public static final ChainStrategy NEVER

The operator won't be chained with any operator.

方法详细资料

values

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