copy

问题 Imagine that I have a shared folder MyShared: User A, gets the file \MyShared:\Foo.txt after every 30 seconds. And I overwrite \MyShared:\Foo.txt also after every 28 seconds (within my PowerShell script) How can I prevent myself to overwrite this file while the user is getting it, in PowerShell? (I do not want to break the content of the file or end-up with some error by attempting to overwrite it in the time of user retrieving it) If I rephrase the question : How can I force a Powershell

问题 Can someone guide me on a possible solution? I don't want to use /bin/cp or any other foreign apps. I want my program to be independent. Also I know that every system is quite specific, so I'm interested in UNIX/Linux compatibility. How can I solve it? Just going down the source directory and creating a new directories in the target one and copying files in them, or there is a better solution? BTW my goal is: copy all first level subdirs recursively into target dir if they are not present

问题 I would like to make a deepcopy of a function in Python. The copy module is not helpful, according to the documentation, which says: This module does not copy types like module, method, stack trace, stack frame, file, socket, window, array, or any similar types. It does “copy” functions and classes (shallow and deeply), by returning the original object unchanged; this is compatible with the way these are treated by the pickle module. My goal is to have two functions with the same

问题 I simulate an evolving population in Julia. Somewhere in my code I randomly sample (sample weighted by the fitnesses of the individuals) individuals in order to form the next generation. Because the same individual can be sampled several times (sampling with replacement), I have to make that I copy the individuals and not only create a new pointer to the same data. Here is what the code looks like for the moment: ##### Reproduction ###### NewPopulation = Array(Individuals, nb_individuals_in

问题 My application stores my web service responses into WeakHashMap. In my application I manipulate the data coming back from the web service in UI, and since the objects are being referenced it also modifies the reference (In my weak hashmap). Is there a way to store a copy of the objects into my hashmap instead of a reference, without having to implement Clonable on every single Model object in my application? 回答1: Kryo allows serialization with minimal effort. It's also should be very
