枚举 BinaryOperator

java.lang.Object

java.lang.Enum<BinaryOperator>

ai.rapids.cudf.ast.BinaryOperator

所有已实现的接口

Serializable, Comparable<BinaryOperator>

public enum BinaryOperator
extends Enum<BinaryOperator>

AST 运算符的枚举，可出现在二元操作中。注意：此枚举必须与 CompiledExpression.cpp 中的 `jni_to_binary_operator` 保持同步！

方法详细信息

values

public static BinaryOperator[] values()

返回一个数组，其中包含按声明顺序排列的此枚举类型的常量。此方法可用于按如下方式迭代常量

for (BinaryOperator c : BinaryOperator.values())
    System.out.println(c);

返回

一个包含按声明顺序排列的此枚举类型的常量的数组

valueOf

public static BinaryOperator valueOf(String name)

返回具有指定名称的此类型的枚举常量。字符串必须与用于在此类型中声明枚举常量的标识符完全匹配。（不允许有多余的空白字符。）

参数

name - 要返回的枚举常量的名称。

返回

具有指定名称的枚举常量

抛出

IllegalArgumentException - 如果此枚举类型没有具有指定名称的常量

NullPointerException - 如果参数为 null
