Introduction The implementation of this class is tailored for Microsoft Windows However, the interface is designed to conceal system-specific behavior The BitmapImage class has two main storage areas: the color map and the pixel data An pplication can store an image in a BitmapImage object by using one of the image decoders in this book (or one you write yourself) or by using the SetSize, ColorMap, and [] operators to write store raw image data SetSize The SetSize function allocates the dynamic memory used to store image data within a BitmapImage object An application must call this function before attempting to store image data into the object ColorMap The ColorMap functions are used to access the image's color palette For images with a bit depth of 8 or fewer the application must fill in the color map If the image has a bit depth of 24 this function should not be used [] (Subscript) Operator The subscript operator is used to access individual bytes in the image pixel data The format of this data depends upon the bit depth of the image For images that use 8 bits per pixel each data byte is an index into the color map (accessed through the ColorMap functions) If the bit depth is fewer than 8, multiple color indices are packed into the data bytes The higher-order bits contain the leftmost pixel values For 24-bit images each pixel is represented by 3 bytes The usual ordering for color bytes in a 24-bit image is RGB, but Windows expects the values in BGR order The BitmapImage class defines the values RedOffset, GreenOffset, and BlueOffset used by the programming examples to specify the ordering of these bytes If your system does not use BGR ordering, you can change the values of these offsets Another Windows'ism that the subscript operator conceals is Windows images will be stored starting with the bottommost row In order to make displaying an image as easy as possible on Windows, this implementation of the BitmapImage class stores the rows in bottom-to-top order, as Windows expects them to be However, the subscript operator reverses the row order so that [ ] 0 returns the topmost row of the image Windows also expects the length of each image row to be a multiple of 4 bytes The subscript operator automatically takes this padding into account so that [N][0] always returns the first pixel byte for the Nth row By making the implementation of BitmapImage independent of the interface it is possible to change the implementation to support different systems without affecting the image encoders and decoders There are two implementations of the subscript operator If the CHECK_RANGE preprocessor symbol is defined, the subscript operator performs range checking on all values If CHECK_RANGE is not defined, no range checking is done The.

Typesafe enums are, generally speaking, comparable in performance to int enumeration constants Two distinct instances of a typesafe enum class can never represent the same value, so reference identity comparisons, which are fast, are used to check for logical equality Clients of a typesafe enum class can use the == operator instead of the equals method; the results are guaranteed to be identical, and the == operator may be even faster If a typesafe enum class is generally useful, it should be a top-level class; if its use is tied to a specific top-level class, it should be a static member class of that top-level class (Item 18) For example, the javamathBigDecimal class contains a collection of int enumeration constants representing rounding modes for decimal fractions These rounding modes provide a useful abstraction that is not fundamentally tied to the BigDecimal class; they would been better implemented as a freestanding javamathRoundingMode class This would have encouraged any programmer who needed rounding modes to reuse those rounding modes, leading to increased consistency across APIs The basic typesafe enum pattern, as exemplified by both Suit implementations shown earlier, is fixed: It is impossible for users to add new elements to the enumerated type, as its class has no user-accessible constructors This makes the class effectively final, whether or not it is declared with the final access modifier This is normally what you want, but occasionally you may want to make a typesafe enum class extensible This might be the case, for example, if you used a typesafe enum to represent image encoding formats and you wanted third parties to be able to add support for new formats To make a typesafe enum extensible, merely provide a protected constructor Others can then extend the class and add new constants to their subclasses You needn't worry about enumeration constant conflicts as you would if you were using the int enum pattern The extensible variant of the typesafe enum pattern takes advantage of the package namespace to reate a magically administered namespace for the extensible enumeration Multiple organizations can extend the enumeration without knowledge of one another, and their extensions will never conflict Merely adding an element to an extensible enumerated type does not ensure that the new element is fully supported: Methods that take an element of the enumerated type must contend with the possibility of being passed an element unknown to the programmer Multiway branches on fixed enumerated types are questionable; on extensible enumerated types they're lethal, as they won't magically grow a branch each time a programmer extends the type One way to cope with this problem is to outfit the typesafe enum class with all of the methods necessary to describe the behavior of a constant of the class Methods that are not useful to clients of the class should be protected to hide them from clients while allowing subclasses to.

A company s managers make a number of small, incremental decisions related to employee benefits over time, frequently resulting in a wide array of benefits whose true cost is much higher than expected Frequent use of this measurement tends to result in a much more conservative view of suggested additions to the existing benefits pool Also, knowing the benefit cost per person allows one to make decisions regarding whether it is less expensive to use contractors on a higher perhour basis or hire new employees at a lower hourly rate, but with benefits Benefit costs are best measured on a per-person basis, so the measurement should include all benefit costs in the numerator and the total number of full-time equivalent employees in the denominator Benefit costs should include time taken off for vacations and sick time, all types of medical insurance (such as medical, dental, life, and disability insurance) net of employee deductions, and miscellaneous benefits, such as club memberships, dry cleaning costs, and company cars The measurement is: Total cost of time off + Insurance + Other benefits Employee deductions Number of full-time equivalent employees For example, the Sod Software Company, maker of operating systems for farmers, has assembled a high-powered group of 40 developers who have been attracted by the company and retained in large part by its excellent benefits package Nonetheless, the company is finding that the package is extremely xpensive, and must determine if any further additions to its staff should be outside contractors who require no benefits The payroll staff assembles the following annualized benefits information: Benefit Type Medical insurance Dental insurance Long-term disability Short-term disability Vacation time Sick time Company cars Health club memberships Totals Total Cost $238,000 29,000 11,000 27,000 80,000 9,000 40,000 14,000 $448,000 Total Deductions $23,800 2,900 0 0 0 0 0 0 $26,700 Net Total Cost $214,200 26,100 11,000 27,000 80,000 9,000 40,000 14,000 $421,300.
