stack

问题 I been working on Android Native App , What i was trying to do is : Activities - A -> B -> C Then A-> B -> C -> C . From C Activity if it again point to C then i want to remove C , B from stack manually . On my back it should move only to A . I tried finish() but problem is : Activities - A -> B -> C Then A-> B -> C -> C on finish A -> B -> C required state A-> C . Is anyone know how to catch all activities in stack and remove specific activities from stack ?? 回答1: In Activity C, override

问题 In my java web application, I have a single background-worker thread, which requires a lot of stack space, because it runs a really complex workflow using the activiti workflow engine and groovy script tasks. Currently I need to set the JVM Xss setting as high as 16MB on a 64bit Java and Tomcat, to circumvent any StackOverflowErrors. If the error occurs the stack trace is really huge (several hundred lines long) but it all happens inside the engine, so I can't really do anything about it. Now

问题 In c++ how can I print out the contents of my stack and return its size? std::stack<int> values; values.push(1); values.push(2); values.push(3); // How do I print the stack? 回答1: You could make a copy of the stack and pop items one-by-one to dump them: #include <iostream> #include <stack> #include <string> int main(int argc, const char *argv[]) { std::stack<int> stack; stack.push(1); stack.push(3); stack.push(7); stack.push(19); for (std::stack<int> dump = stack; !dump.empty(); dump.pop())

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 months ago . Does anyone know some tools to create a call tree for C application that will run on a microcontroller (Cortex-M3)? It could be generated from source code (not ideal), object code (prefered solution), or at runtime (acceptable). I've looked at gprof, but there's still a lot missing to get it to work on an

问题 I want to know what's the use of -mpreferred-stack-boundary option during compilation in GNU compiler. I've checked the documentation but the explanation is lost on me. Could someone please explain it. 回答1: I want to know what's the use of -mpreferred-stack-boundary option during compilation in GNU debugger. The option has absolutely nothing to do with the debugger. It affects generated code in your binary. By default, GCC will arrange things so that every function, immediately upon entry,

问题 I read lot of articles about garbage collection and almost all article tells about heap memory. so my question is "garbage collection collects stack memory or heap memory or both". 回答1: It collects heap memory. Usually, stack memory is collected automatically when the execution path reaches the end of the scope. e.g.: void fun() { int n; // reservation on the stack as part of the activation record ... } // returning the stack pointer to where it was before entering the scope In fact, in a

问题 Everything below is from the main page of www.pythontutor.com (a fantastic tool and website by the way). Here's some code Here's what the author describes as the "global frame" and the "stack frames" at the current point of execution for the above code: My question: What's the difference between "global frame" and the "stack frame"? Is this terminology even correct (I googled around and got all kinds of different answers)? 回答1: frames are actual python objects that you can interact with:

问题 All, just wondering if it's possible in .NET/C# to get a list of variables on the stack and their values? I am creating an exception handler for my app and beyond a standard stack trace I'd also like to see the names and values for any variables that are on the stack. Any idea if this can be done? 回答1: Yes, the StackFrame class can help you with that. Linkage Something along these lines var currentStackFrame = new StackFrame(1); var props = currentStackFrame.GetMethod().GetParameters(); 来源：

问题 Suppose I have the following array: int list[3]={2,8,9}; printf("%p,%p,%p",(void*)&list[0],(void*)&list[1],(void*)&list[2]); Is it always guaranteed that &list[0]<&list[1]<&list[2] ? I had assumed it to be a hard and fast rule while using C, but now have to very sure about it as an OP just asked me about it when I answered his question about endianness Little endian or Big endian What gave me second thoughts is the stacks can grow up or down issue.I am not very sure about that so your

问题 I have created a brand new rails project using the command rails new qbc --database=mysql . It creates all the files perfectly fine, but at the bundle install it errors out $ bundle install Fetching gem metadata from https://rubygems.org/...........
