Java序列化，ObjectInputStream.readObject（），检查是否会阻塞 [英] Java serialization, ObjectInputStream.readObject(), check if will block

问题描述

我正在使用 ObjectInputStream 来调用 readObject 来读取序列化 Objects 。我想避免使用此方法块，所以我希望使用类似 Inputstream.available（）的内容。

I'm using an ObjectInputStream to call readObject for reading in serialized Objects. I would like to avoid having this method block, so I'm looking to use something like Inputstream.available().

InputStream.available（）会告诉你有可用的字节，并且 read（）不会阻止。是否存在一种等效的串行化方法，它会告诉您是否有对象可用且 readObject 是否会阻塞？

InputStream.available() will tell you there are bytes available and that read() will not block. Is there an equivalent method for seriailzation that will tell you if there are Objects available and readObject will not block?

推荐答案

不。虽然您可以在另一个线程中使用 ObjectInputStream 并检查是否有可用的对象。一般来说，轮询并不是一个好主意，特别是对于 InputStream.available 的保证不佳。

No. Although you could use the ObjectInputStream in another thread and check to see whether that has an object available. Generally polling isn't a great idea, particularly with the poor guarantees of InputStream.available.
