问题 How can I ensure that an element is in my HASH_TABLE, if it is detachable? Current = HASH_TABLE[ARRAYED_SET[G], G] add_edge (src: G; dst: G) do if attached Current.at(src) as edges then edges.put(dst) end ensure in: Current.at (src).has (dst) end 回答1: Have you try that: add_edge (src: G; dst: G) do if attached Current.at(src) as edges then edges.put(dst) end ensure in: attached Current.at (src) as edges implies edges.has (dst) end 来源： https://stackoverflow.com/questions/20935201/detachable

问题 I am trying to remove an object and store it (in case a user wants to retrieve it later). I have tried storing the object in a variable like it says in the thread below: How to I undo .detach()? But the detach() does not remove the element from the DOM or store it. I am also not getting any error messages. Here is the code I am using to detach the element: function MMtoggle(IDnum) { var rowID = "row" + IDnum; var jRow = '#' + rowID; thisMMbtn = $(jRow).find(".addMMbtn"); var light = false;

问题 I want to get a domain entity in grails in detached state when there is another domain entity for same id in same method. I followed this How do you disconnect an object from it's hibernate session in grails? as a way to get a detached domain entity in grails. def id = 23L; def userInstance = User.get(id) def oldInstance = User.get(id).discard() userInstance.properties = params userInstace.save(flush:true) // Now, I want to compare properties of oldInstance and userInstance // But I get null

问题 I have class Person mapped to database with NHibernate. I load objects from DB and send it to different clients. First client will modify Name and Country property. Second client will modify only Name property. Then both returns modified objects to server. When I save data from first client - then saved correctly, both - name and country updated. When I save data from second client - I have problem. It was override data from first client and save new name and initial value of country. How I

问题 I would like to create a process using the mutliprocessing module in python but ensure it continues running after the process that created the subprocess exits. I can get the required functionality using the subprocess module and Popen, but I want to run my code as a function, not as a script. The reason I want to do this is to simplify creating pyro (python remote objects) objects. I want to start the pyro object request handler in a separate process using multiprocessing, but then I want

问题 In git if you checkout a commit directly you get a big fat warning starting with: "You are in 'detached HEAD' state. You can look around ..." It's fine - I intend to be in detached HEAD state. However I am using this in a script and I don't want this warning in the output logs but I do want the normal output. My "ugly" workaround now is to run the same command twice, first with -q to hide the warning, and one more time to get the normal output: HEAD is now at deadbeef... Message since the

问题 In bash , I can do the following: for f in subdir/*.sh; do nohup "$f" "$@" &> /dev/null & done in other words, it runs all *.sh scripts in subdir in the background, and detached so that if the main script ends, the background scripts won't be terminated. Now, let's say I have the following Python project: proj/ __init__.py main.py subdir/ __init__.py mod_a.py mod_b.py mod_c.py How do I do something similar to the bash script? But with parameters passed as Python objects? E.g.: I have two

问题 I would like to develop a web-app requiring data persistence using GWT and GAE. As I understand it, my only (or at least by far the most convenient) option for data persistence is GAE's Datastore, using JDO or JPA annotated objects. I would also like to be able to send my objects back and forth client-server using GWT Remote Procedure Calls (RPC), therefore my objects must be able to "detach". However, GWT RPC serialization cannot handle detached JDO/JPA objects and it doesn't appear as

问题 What is different between join() and detach() in multi threading in C++? Does join() kill the thread? 回答1: A C++ thread object generally (but not always) represents a thread of execution, which is an OS or platform concept. When thread::join() is called, the calling thread will block until the thread of execution has completed. Basically, this is one mechanism that can be used to know when a thread has finished. When thread::join() returns, the OS thread of execution has completed and the C++
