什麼是@deprecated in java的反向

Question

所以，人們對已棄用的API使用@Deprecated註釋。

是否有任何註釋可以通知用戶該方法是否正在發展並且不穩定？

Answer 1

Afaik，它還不存在，你必須創建自己的。

JEP277定義@Deprecated(EXPERIMENTAL)，但它只是一個命題。

Answer 2

在hadoop中有InterfaceStability註釋用於這些目的。有趣的是這個註釋並不穩定。我懷疑JDK中會出現這樣的事情。

@InterfaceAudience.Public 
@InterfaceStability.Evolving 
public class InterfaceStability { 
    /** 
    * Can evolve while retaining compatibility for minor release boundaries.; 
    * can break compatibility only at major release (ie. at m.0). 
    */ 
    @Documented 
    public @interface Stable {}; 

    /** 
    * Evolving, but can break compatibility at minor release (i.e. m.x) 
    */ 
    @Documented 
    public @interface Evolving {}; 

    /** 
    * No guarantee is provided as to reliability or stability across any 
    * level of release granularity. 
    */ 
    @Documented 
    public @interface Unstable {}; 
}
