sum of the memory that the object can be recycled to after it has been GC. For a better understanding of retained size, consider an example.The objects in memory are treated as nodes in, and objects and objects are referenced to each other. Here's a special node GC Roots, Positive solution! This is the beginning of reference chain. Starting with obj1, the middle blue node represents only objects that can be accessed directly or indirectly through OBJ1. Because it can be accessed through GC root

attributes defined in the DFA's state are also used by the DFA and Index to facilitate state use. Second, NFA conversion to DFA 2.1 Subset Construction method The NFA is converted to a DFA, and a subset construction (subset construction) algorithm is used. The process of the algorithm is similar to the NFA matching process mentioned in section 3.1 of the C # lexical Analyzer (iii) regular expression. In the NFA matching process, use is a state of

Calculator is a lot of programming beginners have done, starting from the simplest console program, input values, input operators, and then enter a value, to get a result. The interface is basically modeled on the Windows operating system calculator, through the button input values and operators, and then give the results of the operation. Can you directly enter an expression, or you can calculate several expressions, or select a part of an expression to calculate, if the input error can indicat

With the SPA, you can play specific types of changes depending on the type of change (such as initialization of change, optimizer statistics refresh, and database upgrade)SQL or the entire SQL payload, and then generate a comparison report that helps you evaluate their impact.In the version number prior to Oracle Database 11g, I had to capture all the SQL statements and execute them by tracing,Then get the run plan-this is a very time-consuming and error-prone task.

After making the analyzer report, you want to be able to copy directly to other machines (unable to connect over the network)The method is simple:1. Enter the analyzer's Database server Settings page to find out which system database is connected2. Back up the system database3. Cubes used to back up the report4. Restore the system database and cubes to a new machineNote: If you can connect directly through the network, you can directly connect to the

A notable feature of the prediction-based Grammar analyzer is to define a non-Terminator as a parsing function (method). When a non-terminator can be derived as another non-Terminator, recursively call the parsing function. One disadvantage of this method is that it is difficult to handle the situation that requires backtracking. We will analyze it in detail later. The last time we studied the parsing of individual characters such as Cr, lf, and htab,

In the previous article, we introduced how to use the Intel compiler to improve program performance by improving the execution efficiency after program compilation. However, to improve the software performance, you can not only improve the compilation and Execution Code, but also analyze the program performance to identify performance bottlenecks and focus on optimization. Intel vtune visual performance analyzer is an analysis tool provided by Intel f
