EJB entity beans also support aggregate or multirow functions However, these are coded in the home interface part of the bean because they apply to a set of bean instances We'll discuss an example of a home interface business method in the following subsection Coding the Home Interface The home interface for an entity bean needs to provide factory-like instance creation methods, just like the home interface for a session bean However, in addition to these methods, are two others are unique to entity beans the so-called finder methods and the home-interface business methods As for creating an entity bean via the home interface create() API call, keep in mind that this action implies something different than it does for session beans Instead of creating a running instance of a bean, an entity bean instantiation directly corresponds to inserting a row into a database This makes sense: Entity beans are persistent, so creating them should mean that they'll persist until they're deleted The finder methods provided by the home interface of an entity bean distinguish asubset of instances (or just one instance) from all the others You can add any finder methods that you want for your entity bean, but at least one is required, findByPrimaryKey(), which takes the object corresponding to the primary key as its parameter and returns a unique bean instance Finder methods that return more than one instance typically do so by returning a javautilCollection (enumerations are also supported) With bean-managed persistence, it's obviously up to the developer to write the JDBC and SQL to find subsets of instances This is coded in the bean implementation class, as we'll see shortly With container-managed persistence, however, the container actually does all the work The only requirement is that the deployment metadata include enough information on how to build the WHERE clause of the underlying query With EJB 20, it's now possible for deployers to use the new J2EE EJB query language, EJB-QL, to accomplish this task The details of EJB-QL are beyond the scope of this book Rather, our aim here is to understand that container-managed persistence provides enough underlying support so that no database code is required of the developer If the ethod signa ture and some deployment metadata is provided, all of the necessary database integration can be accomplished automatically by the container.

CompositingMode may be helpful in scenarios where you need to draw overlapped images Suppose you draw one rectangle and one ellipse, and an area of the ellipse overlaps a small area of the rectangle You may or may not want to show the overlapped area of the rectangle The compositing mode provides you the option of doing either Instead of applying CompositingMode to all of the graphics, you can apply it to selected shapes One way to do this is to create a temporary Graphics object (a new surface), draw all the shapes you need and apply the compositing mode on this object You can also create graphics containers and apply the necessary settings to each graphics container The quality of compositing is inversely proportional to the rendering speed: The higher the quality, the slower the rendering The CompositingQuality property of the Graphics object represents the quality of a composition process, which takes value of type CompositingQuality enumeration The CompositingQuality enumeration is defined in Table 912 Listing 933 draws two sets of shapes Each set has a rectangle and an ellipse First we create a Bitmap object, and then we create a temporary Graphics object using the FromImage method by passing the Bitmap object We set the CompositingMode property of this Graphics object to SourceOver, which means that the color rendered overwrites the background color Then we draw a rectangle and an ellipse.

Each raster output device has a native color space, which typically is one of the standard device color spaces (DeviceGray, DeviceRGB, or DeviceCMYK) In other words, most devices support reproduction of colors according to a grayscale (monochrome), RGB (red-green-blue), or CMYK (cyan-magenta-yellow-black) model If the device supports continuous-tone output, reproduction occurs directly Otherwise, it is accomplished by means of halftoning A device s native color space is also called its process color model Process colors are ones that are produced by combinations of one or more standard process colorants Colors speci ed in any device or CIE-based color space are rendered as process colors (A evice can also support additional spot colorants, which can be painted only by means of Separation or DeviceN color spaces They are not involved in the rendering of device or CIE-based color spaces, nor are they subject to the conversions described below) Note: Some devices provide a native color space that is not one of the three named above but consists of a different combination of colorants In that case, conversion from the standard device color spaces to the device s native color space is performed by device-dependent means Knowing the native color space and other output capabilities of the device, the viewer application can automatically convert the color values speci ed in a document to those appropriate for the device s native color space For example, if a document speci es colors in the DeviceRGB color space but the device supports grayscale (such as a monochrome display) or CMYK (such as a color printer), the viewer application performs the necessary conversions If the document speci es colors directly in the device s native color space, no conversions are necessary The algorithms used to convert among device color spaces are very simple As perceived by a human viewer, the conversions produce only crude approximations of the original colors More sophisticated control over color conversion can be achieved by means of CIE-based color speci cation and rendering Additionally, device color spaces can be remapped into CIE-based color spaces (see Default Color Spaces on page 194).

related graphics state parameters to compute its result This mode applies only when painting elementary graphics objects ( lls, strokes, text, images, and shadings) It is never invoked explicitly and is not identi ed by any PDF name object; rather, it is implicitly invoked whenever an elementary graphics object is painted while overprinting is enabled (that is, when the overprint parameter in the graphics state is true) Note: Earlier designs of the transparent imaging model included an additional blend mode named Compatible, which explicitly invoked the CompatibleOverprint blend mode described here Because CompatibleOverprint is now invoked implicitly whenever appropriate, it is never necessary to specify the Compatible blend mode for use in compositing It is still recognized as a valid blend mode for the sake of compatibility, but is imply treated as equivalent to Normal The value of the blend function B(cb , cs ) in the CompatibleOverprint mode is either cb or cs , depending on the setting of the overprint mode parameter, the current and group color spaces, and the source color value cs :.
