In this chapter we discuss the pitfalls of mitigating synchronization methods-synchronizing code blocks.1. Thinking: Synchronize the method, reduce the granularity of synchronization, synchronization to the code block2. According to the example in the previous section, we modified the code(1) The first method, the synchronization tag to move to the updated column, in general, most of the updates need to synchronize the dataPackage com.ray.deepintothre

. In this case, you can directly use them outside the class without creating instances of this class. 2. Static variables are a reference. This situation is special. The main problem is that the static variable is an object reference, so you must initialize this object before you can point the reference to it. Therefore, to define a reference as static, the object must be initialized during the definition. Static code block: Static code blocks are ma

Finally, we installed the Code: Blocks on the CentOS virtual machine. I felt a lot and learned a lot. Focus on step 2 of the installation step and set environment variables.

There is an overhead space (overhead) at the beginning of the database block, which stores a transaction table for the block. For each "actual" transaction that locks some data in the block, there is a corresponding entry in this transaction table. -> Http://www.bkjia.com/database/201110/108943.html 1) when a transaction starts, a transaction slot needs to be allocated to the transaction table in the rollback segment; 2) Obtain an ITL transaction slot in the data block header, which points to th

Pass Value Blocks is an extension of the C language: An anonymous function with an automatic variable (local variable). With blocks, anonymous functions can be used in the source code, that is, functions without names. In our work, name occupies a large part, function name, variable name, property name, class name, frame name, etc. must have. Being able to write a function without a name is q

The root directory of the Code corresponds to the workspace, and each subdirectory corresponds to a project. This can avoid the disadvantages of slow tags Library Creation by codelite. The benefit of the software is that the features that come up with it will be added. Unlike commercial software, some of the necessary features will not be released for a long time.
