英文:
Two enum constants in Kotlin with the same value
问题
在Kotlin中是否可以为枚举常量创建一个'alias'（别名），以便可以通过两个名称引用同一个枚举常量？
例如：如果MyEnum是一个包含两个常量A1和A2的枚举的名称，那么MyEnum.B1应该与MyEnum.A1实际上是相同的，MyEnum.B2应该与MyEnum.A2实际上是相同的。
英文:
Is it possible to create an 'alias' for an enum constant in Kotlin, so that its possible to refer to one single enum constant by two names?
Eg: If MyEnum is the name of the enum with 2 constants A1 and A2, then MyEnum.B1 should effectively be the same as MyEnum.A1 and MyEnum.B2 should effectively be the same as MyEnum.A2.

你可以通过在枚举内部将 'alias' 名称作为静态 val 包含来简单实现此操作。
enum class MyEnum {
A1, A2;
companion object {
val B1 = A1
val B2 = A2
}
}
英文:
You can do this simply by including the 'alias' names as static vals inside the enum.
enum class MyEnum {
A1, A2;
companion object {
val B1 = A1
val B2 = A2
}
}
