问题描述
我们发现在Google Guava中使用AddListener补充RemovalListener非常有用.
We'd find it very useful to have an AddListener to complement RemovalListener in Google Guava.
AddListener是否有合适的替代品，可以补充RemovalListener?
Is there a suitable alternative to an AddListener that would complement RemovalListener?
推荐答案
您可以自己提供-只需将自定义侦听器传递给计算Function，并且每当计算一个值时，都将通知侦听器.
You can provide that yourself - just pass your custom listener to your computing Function, and whenever you compute a value, notify the listener.
如果您使用的是asMap().put(..)，则必须将整个内容包装在您的自定义类中，该类既委托原始对象，又调用附加侦听器.
If you are using asMap().put(..), then you'd have to wrap the whole thing in in your custom classes that delegate to the originals but also invoke the addition listener.
