after all events have been processed, and there is no problem even if the deletelater is called multiple times. Four,Smart Pointers1.QpointerQpointer is a template class that Qpointer can monitor dynamically allocated space objects and update them when the object is deleted.Qpointer: In Qpointer, a qobject pointer is saved and the pointer (double pointer) is given to the global variable management, while the Qobject is destroyed (the destructor, Qwidget, is through its own destructor, Instead o

:) ========================================================== ============================ 4. Of course, it is best to use the log clearing tool. Enter a few commands for the program to help you clean :) A. Common log clearing tools. General rootkit packages include z2.c and wted. C. It is easy to find. Many online tutorials describe the use of these two tools. I will not discuss it here. :) save time. B. Here I provide a script that I used to clear logs for a while.

cleaner. Congcong COKIN lens water is to the lens due to moisture caused by the mildew of the mildew spots to clear the role, and has a moderate anti-mildew effect. The cleaning liquid (20% ethanol + 80% ether) is mainly used to clear water stains and oil stains (fingerprints) on lenses ). Be careful when using LCD screens and other plastic products. COKIN R906 wet wipe mirror paper has the role of the above cleaning liquid, more anti-static, dust re

In the face of the ever-expanding Linux system, the space on your hard disk is increasingly stretched. How to lose weight in Linux can usually be done manually or using system tools. This article introduces the following tools: ActivityLogManager, BleachBit, find, fdupes In the face of the ever-expanding Linux system, the space on your hard disk is increasingly stretched.

Netty itself supports heap memory and direct memory on memory allocations, and we generally choose Direct memory, which is also the default configuration. So to understand the release of Netty memory we have to look at the release of direct memory first.Java Direct Memory ReleaseLet's take a look at how direct memory is used.ByteBuffer.allocateDirect(capacity)The application process is actually the process of creating a Directbytebuffer object, the Directbytebuffer object is only equivalent to a

plastic used to manufacture dust-proof covers will gradually age and release the contaminated gas. The dust cover surface may also contain the demoulding material used during high-speed production. The correct cleaning product and steps must be followed. In fact, the cleaning method is not correct, not only the cleaning effect is poor, but also may cause damage. Although canned gas has been used as a dust removal method for many years, it cannot remove small electrostatic particles, and will fo

%, creating a mechanism similar to garbage collection.QpointerQpointer is a template class. It is similar to a normal pointer, except that Qpointer can monitor dynamically allocated objects and update them when the object is deleted. Qpointer behaves like a normal pointer Qdate *mydate = new Qdate (Qdate::currentdate ()); Qpointer mypointer = MyData; Mydate->year (); ///2005 Mypointer->year (); ///2005 Qpointer will behave differently when the object is delete Delete mydate;

QDate * mydate = new QDate (QDate: currentDate ()); QPointer mypointer = mydata; Mydate-> year (); //-> 2005 Mypointer-> year (); //-> 2005 // After the object is deleted, QPointer has different performances. Delete mydate; If (mydate = NULL) Printf ("clean pointer "); Else Printf ("dangling pointer "); // Output dangling pointer If (mypointer. isNull ()) Printf ("clean poin

Generally, lkm is used to provide additional functions for the system without re-compiling the kernel, such as loading device drivers and other hardware drivers. Linux, Solaris, and BSD (free, net, and open) operating systems allow the ability to load kernel modules to implement certain system functions. Some rootkit can use this mechanism to run itself as a kernel-loaded module, and cheat the application at the kernel layer without modifying the application itself, therefore, it is better conce

Storm uses a data structure called timecachemap to store recently active objects in the memory. It is highly efficient and automatically deletes expired and inactive objects. Timecachemap uses multiple buckets to narrow the lock granularity, in exchange for high concurrent read/write performance. Next, let's take a look at how timecachemap is implemented internally. 1. Implementation Principle Bucket linked list: each element in the linked list is a hashmap used to save data in key and v

Windows XP System Optimization Acceleration Method Daquan: ① Select Start Run, type regedit, expand Hkey_current_usercontrol paneldesktop, change the value of the string value "Hungapptimeout" to 200, and then the string value " Waittokillapptimeout "Value data changed to 1000; ② also under Hkey_local_machinesystemcurrentcontrolsetcontrol, change the value data of the string value "Hungapptimeout" to 200, and the string value " WaitToKillServiceTime

when the outer heap of memory in the Directbytebuffer is released. Brief Answer Directbytebuffer when allocating the heap of memory: first, through the bits.reservememory to see if there is still available memory, whether the maximum amount of memory in the heap is reached. If anything, take up the pit. Allocates memory through Unsafe.allocatememory. Create Cleaner, this Cleaner is used to manage the hea

understand the above content. As long as the content is simple, it is not difficult to achieve. When you want to cache more complex content, you need to make trade-offs. Because the page you want to cache is highly dynamic, the expiration logic becomes more complex. To handle complex expiration failure logic, you will need to write and configure a custom cleaner (sweeper). When some controllers are fired, the classes delete the selected elements fro

Which files in Linux are spam files? After the Linux computer is installed, during our continuous use, various junk files will be generated in the hard disk due to activities such as adding and deleting software and surfing the Internet, debugging programs, etc, as these junk files continue to expand, they will not only flat our valuable hard disk space, but also drag down the running speed of the machine and affect our work efficiency. This article describes how to use the tool and weight loss
