Author: gnuhpcSource: http://www.cnblogs.com/gnuhpc/ First, you need to understand that in Linux, the kernel assigns an inode (index node) to each newly created file, and each file has a unique inode number. The file attributes are stored in the index node. when accessing the file, the index node is copied to the inner to implement fast file access. A link is a way to establish a connection between a shared file and several directory items of the users who access it. Linux contains two types of

, if this o is a global variable, you will need to assign NULL when you do not use this object, because a strong reference is not garbage collected.The Strong reference is very important in practice, for example, a ArrayList implementation source code: privatetransient object[]elementdata; publicvoidclear () { modCount++; //letgcdoitswork for (inti=0;isize;i++) elementdata[i]=null; size= 0;} A private variable elementdata array is defined in the ArrayList class, and you can see th

As we all know, Java is the JVM responsible for the allocation and recycling of memory, which is its advantage (easy to use, the program no longer like using C as the memory), but also its shortcomings (not flexible). In order to solve the problem that memory operation is not flexible, we can adopt soft reference method.In previous versions of JDK1.2, when an object was not referenced by any variable, the program could no longer use the object. That i

Objective:Android developers know that the memory usage of mobile devices is a very sensitive topic, today we look at how to use soft references and weak references to optimize memory usage. Here are a few concepts to understand.1.StrongReference (Strong reference)Strong reference is one of our most common, generally we in the code directly through the new object, and so on, are strong references, strong references as long as the existence is not dest

Recent company project requirements on our ipad project on some need to enter a number of places with our custom soft keyboard and not mobile device comes with the keyboard, just received a little bit of a confused, because did not have done before, and then a bit of thought to find this thing is that. Let's look at the results after the implementation:The effect is that when you click on the page needs to pop the

GuideThere are two types of Linux links, one called hard links, and the other called Symbolic links (symbolic link). By default, the LN command produces a hard link. The difference between the hard link and the soft link fundamentally starts with the Inode node, and the following example explains the creation of hard links and soft links in Linux systems, to actually look at the differences between the two

Describe:Link- -is a way to establish a connection between a shared file and a number of directory entries for the user who accesses it. There are soft links and hard links (soft link) in Linux, where soft links are also called Symbolic links (symbolic link). Index nodes : The management of files in Linux systems is essentially managed by their index nodes. Fro

Hard Link ConceptsA hard link, also called a link, is one or more filenames of a fileAfter the hard link is established, the source file and the link file are synchronized, and any one of the files will be modified.Create links to save space, just maintain link relationships and don't need to copy filesthe essential difference between hard and soft links a hard link can be thought of as a file with two filenames, whereas a

Hard LinksThe new file is an alias for a file that already exists, and the new file is still available when the original file is deleted.Hard Link Features:1, with the same I node and the same storage block fast, can be seen as the same file2, can be identified through the I node, I node number is the same3, not across partitions4, not for directory use5, delete files, the normal use of hard links Soft linksAnother connection, called a symbolic connec
