您可以通过编写::test(或this::test)来引用吸气剂.

You can reference the getter by writing ::test (or this::test).

编写test::get时，实际上是在String上引用get方法.该方法获取一个索引并返回该索引处的字符.

When you write test::get, you are actually referencing the get method on String. That method takes an index and returns the character at that index.

如果该属性是var，并且您想要引用其setter，则可以编写::test::set.

If the property was a var and you want a reference to its setter, you can write ::test::set.
