In C++, dynamic binding happens when a virtual function is called through a reference (or a pointer) to a base class The fact that a reference (or pointer) might refer to either a base- or a derivedclass object is the key to dynamic binding Calls o virtual functions made through a reference (or pointer) are resolved at run time: The function that is called is the one defined by the actual type of the object to which the reference (or pointer) refers Make Barcode In NET Using Barcode encoder for NET Related: .

Huffman Table Generation A PNG encoder can either use the fixed Huffman codes shown in Table 149 or generate Huffman codes based on usage frequencies It is simpler to implement fixed Huffman codes but there is obviously a penalty when it comes to compression Unless you are working with an application where compression speed is critical, there is really no reason to use fixed Huffman codes 6 covered Huffman coding as it applies to JPEG The same process with a few modifications will work with a Huffman encoder The differences between Huffman table generation in JPEG and PNG were listed in the previous chapter When we used Huffman coding in JPEG, we generated the Huffman table by making two nearly identical passes over the image data The first pass gathered usage frequencies After generating the Huffman tables from the usage frequencies, the second pass repeated the steps of the first pass except that the data was Huffman encoded Such a scheme can be used to encode PNG image ata but there are a couple of significant drawbacks The main problem with having two nearly identical passes is the time required to compress an image The process of searching the LZ77 window for matching strings is significantly more processing intensive than is JPEG entropy encoding Performing PNG compression process twice lengthens the compression time noticeably A good solution to this problem is to store the literal/length and distance codes in a buffer A simple method for implementing such a buffer would be to.

Memory management is a key aspect of using the server-side C++ mapping The simple example we have shown in the previous sections has avoided issues related to memory management in order to focus on servant class definitions As with the client-side rules described in 7, the server-side parameter passing rules are motivated by two overriding requirements Location transparency Memory management must be the same whether or not the client and target object are collocated Efficiency Copying of parameters must be avoided whenever possible, especially when the client and target object are collocated Not surprisingly, the server-side parameter passing rules are essentially a mirror image of the client-side rules, thus allowing for efficient dispatch for collocated objects The parameter passing rules presented here follow the same order as their presentation in Section 714 for the client side If you are not yet comfortable with the differences between fixed- and variable-length types and hich IDL types fall into each category, please review Section 7141 before continuing.
