This chapter continues to describe the remaining tables that have not been involved. To this end, create a separate program to describe each different table. Finally, in the last chapter of the book, place them in a separate program, where each table is cross-referenced. Table 4-1 The first program in this chapter uses the fields table. Enter the following code in the B. CS file and compile the file. FieldsTable B. CS A. CS Output Instance variables are also called fields. The field table stor

Start the visual editor from Shell VI filename indicates the shell to start the VI editor and pass the filename parameter to it. If the file exists, the VI editor interprets it as the file to be opened. If the file does not exist, the VI compiler creates a new file. VI file1 file2 file3 shell passes three parameters to VI, which is interpreted as the file to be opened by VI. You can run the W command to save the file and run the N command to access the next file. Vi + # filename open the file a

generally an integer multiple of KB, which is related to the CPU L2 cache capacity. It takes 0th kb, 1 Mbit/s to load all data in the generation into the L2 cache of the CPU, which makes data processing faster. 1st generations: If a new object is allocated and the data in the 0th generation exceeds its budget, garbage collection will occur, and data that cannot be reached will be recycled. The first generation has a larger capacity than the

Chapter 8 of python3, python3 We dug a hole in Chapter 4: how to print the 9-9 multiplication table in an elegant way. We will fill in this chapter. First, let's take a look at what the multiplication table looks like. 1 x 1 = 11 x 2 = 2 2 x 2 = 41 x 3 = 3 2 x 3 = 6 3 x 3 = 91 x 4 = 4 2 x 4 = 8 3 x 4 =12 4 x 4 =161 x 5 = 5 2 x 5 =10 3 x 5 =15 4 x 5 =20 5 x 5 =251 x 6 = 6 2 x 6 =12 3 x 6 =18 4 x 6 =24 5 x 6 =30 6 x 6 =361 x 7 = 7 2 x 7 =14 3 x 7 =21 4 x 7 =28 5 x 7 =35 6 x 7 =42 7 x 7 =491 x 8 =

idle, and Unit 2 has been allocated. When an application needs to allocate a memory unit size through the memory pool, it simply needs to traverse all the memory pool block header information and quickly locate the memory pool block with idle units. Then, based on the block header information of the block, you can locate the address of 1st idle units, return the address, and mark the next idle unit. When an application releases a memory pool unit, yo

the above program is not the Function displaymethodtable, but the function displaymethodsignature. In the displaymethodtable function, we started to read the entire method table. However, only the name and signature fields are used, and they store the method signature offset in the Blob stream. After that, the displaymethodsignature function will be called. It has three parameters: the offset in the Blob heap and the offset in the param table (the location of the

several regions, and one thread uses one region. This allows multiple threads to allocate objects at the same time and does not require a thread to exclusively occupy the heap. Scalable Collections: the version of the server (MXSorSvr. dll) that runs the execution engine in a multi-threaded system. The managed heap is divided into several different regions and one CPU area. During initialization, each CPU executes a recycle thread and each thread recycles its own region. The Workstation version
