anonymous

问题 I have a Delphi application which spawns 6 anonymous threads upon some TTimer.OnTimer event. If I close the application from the X button in titlebar Access Violation at address $C0000005 is raised and FastMM reports leaked TAnonymousThread objects. Which is the best way to free anonymous threads in Delphi created within OnTimer event with TThread.CreateAnonymousThread() method? SOLUTION which worked for me: Created a wrapper of the anonymous threads which terminates them upon being Free-ed.

问题 This is probably a simple question, and I'm afraid the answer might be "no", but... Here's a simple piece of code: function func1() { $bt = debug_backtrace(); print "Previous function was " . $bt[1]['function'] . "\n"; } Now... Can this be done without the temporary variable? In another language, I might expect to be able to say: function func1() { print "Previous function was " . (debug_backtrace())[1]['function'] . "\n"; } Alas, in PHP, this results in an error: PHP Parse error: syntax

问题 Consider the following snippet: void Foo() // 1 { } namespace { void Foo() // 2 { } } int main() { Foo(); // Ambiguous. ::Foo(); // Calls the Foo in the global namespace (Foo #1). // I'm trying to call the `Foo` that's defined in the anonymous namespace (Foo #2). } How can I refer to something inside an anonymous namespace in this case? 回答1: You can't. The standard contains the following section ( §7.3.1.1 , C++03): An unnamed-namespace-definition behaves as if it were replaced by namespace

问题 I need to define some constant strings that will be used only by one class. It looks like I have three options: Embed the strings directly into locations where they are used. Define them as private static constant members of the class: //A.h class A { private: static const std::string f1; static const std::string f2; static const std::string f3; }; //A.cpp const std::string f1 = "filename1"; const std::string f2 = "filename2"; const std::string f3 = "filename3"; //strings are used in this

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 6 years ago . The title sums up my question. An example that demonstrates the point would be nice. 回答1: First off, there doesn't seem to be a consensus definition for inline functions in JavaScript. I consider an inline function to be a special case of a JavaScript function. An inline function is a function assigned to a

问题 I have received the following error message when trying to debug an application in NetBeans: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: board.Board$1 In the course of debugging I have had to insert 'implements Serializable' in a number of classes as the exception arose in the course of reading from a file that stores a large object. This has not been difficult as the class needing attention has been clear from the exception message. What has thrown me is

问题 private Student student = new Student(); public Student getStudent(){ return student; } public void function(){ getStudent().setName("john"); } public void function(){ Student student_local = getStudent(); student_local.setName("john"); } Does GC behave differently for both of the snip? I mean which case (CASE-1/CASE-2) is more GC efficient in terms of Time? I simple word GC will be called for CASE-1 or not? 回答1: Amit i've seen your other question, what matters is always only reachability, it

问题 Can you make an anonymous val? I'm thinking to do something like this: case class NumIterations[A](num: Int) case class Seed[A](seed: A) case class Manipulate[A](f: A => A) . . . def funcWithGobsOfImplicitArgs[A]( implicit numIterations: NumIterations[A], seed: Seed[A], manipulate: Manipulate[A], . . . ): A = . . . def apply(): String = { implicit val NumIterations[String](10) // This is where I want anonymous vals implicit val Seed("xyz") . . . funcWithGobsOfImplicitArgs } Okay, making all

问题 I'm creating a library of very common, very simple shapes. Sphere would be a member, as well as torus, and so on. Torus has two radius fields, whereas sphere has one; that modified behavior is something we can provide by changing the implementation of functions to include both radii, and of course, adding the extra radius field. Torus is common enough that inclusion of that behavior in the permanent library is beneficial. On the other hand, "WigglyTorus", a torus whose radii oscillate, would

问题 A recent thread on SO triggerred this. An anonymous namespace is considered to be equivalent to namespace unique { /* empty body */ } using namespace unique; namespace unique { namespace-body } I fail to recollect the exact reason as to why it is not equivalent to namespace unique { namespace-body } using namespace unique; Also tried searching (including google) but in vain. Please share any information you have in this regards. 回答1: The specification that exists now was introduced in 1995 in
