public class NSBundle
extends Object

An NSBundle represents a location in the file system that groups code and resources that can be used in a program. NSBundles locate program resources and assist in localization. You build a bundle in Xcode using a Java WebObjects Application or Java WebObjects Framework project.

NSBundles can be stored on disk in two ways.

The first way is a directory where related resources--including executable code--are stored. The directory, in essence, "bundles" a set of resources used by an application into convenient chunks, and the NSBundle object makes those resources available to the application. NSBundle can find requested resources in the directory. The term bundle refers both to the object and to the directory it represents.

The second way is a java JAR file (Java ARchive). Again, all of the classes and resources are encapsulated into the JAR file. In this case, the term bundle refers to the JAR file itself.

At this point, JAR files are the preferred storage mechanism for NSBundles. However using JAR files requires that java.net.URLs be used to reference resources inside bundles. Path APIs (which typically operate on Strings) cannot be used. All Path APIs in the base WebObjects frameworks should be deprecated.

Bundles are useful in a variety of contexts. Since bundles combine executable code with the resources used by that code, they facilitate installation and localization. NSBundles are also used to locate specific resources and to determine which classes are loaded.

Each resource in a bundle usually resides in its own file. Bundled resources include such things as:

• Images--GIF or JPEG images displayed on web pages
• Localized character strings

Types of Bundles

NSBundle supports two types of bundles: application bundles and framework bundles.

Application Bundles

An application bundle is a bundle that contains the resources needed to launch the application. Its extension is ".woa". To build an application bundle with Xcode, use the Java WebObjects Application project type.

Every application has a single application bundle called the "main bundle". You obtain an NSBundle object corresponding to the main bundle with the mainBundle static method. This is typically the running application itself.

Framework Bundles

A framework bundle is a bundle associated with a framework: a directory containing shared classes along with the resources that go with those classes, such as images and localized strings. A framework directory has a ".framework" extension. To build a framework bundle with Xcode, use the Java WebObjects Framework project type.

You can get an NSBundle object associated with a framework by invoking the static method bundleForName specifying, as the argument, the name of the framework without the ".framework" extension. Alternatively you can invoke the bundleForClass method specifying a class that's defined in the framework. To get all the framework bundles available to your application, you can invoke the frameworkBundles static method.

Bundle Availability

When an application starts up, it loads all of the bundles represented by class path components. If the class path contains multiple framework bundles with the same name, only the first one is loaded; the rest are ignored.

Localized Resources

If an application is to be used in more than one part of the world, its resources may need to be localized for language, country, or cultural region. An application may need, for example, to have separate Japanese, English, French, German, and Spanish versions of the images that label submit buttons.

Resources specific to a particular language are grouped together in a resource directory. This directory has the name of the language (in English) followed by a ".lproj" extension (for "language project"). The application mentioned above, for example, would have Japanese.lproj, English.lproj, French.lproj, German.lproj, and Spanish.lproj directories. The application also has a Nonlocalized.lproj directory, which contains resources shared by all locales.

It is good programming practice to ensure that if a resource appears in one language directory it also appears in all the others. Thus, Icon.gif in French.lproj should be the French counterpart to the Spanish Icon.gif in Spanish.lproj, and so on. However this discipline is not completely necessary. If German.lproj does not contain an Icon.gif resource, the Icon.gif resource in Nonlocalized.lproj will be used instead.

The server's locale determines which set of localized resources will actually be used by the application. NSBundle objects invoke the java.util.Locale.getDefault method to determine the locale and chooses the localized resources accordingly.

How Resources Appear on the File System

A bundle's resources are stored in a directory named Resources within the bundle directory on the file system. Within the Resources directory are all of the language directories except Nonlocalized.lproj. The non-localized resources in the Nonlocalized.lproj directory are mapped into the top level of the Resources directory on the file system.

For example, suppose the NSBundle resources are organized as shown below in Xcode:

                               English.lproj
                                   Edit.wo
                                       Edit.html
                                       Edit.wod
                                       Edit.woo
                               Nonlocalized.lproj
                                   Edit.wo
                                       Edit.html
                                       Edit.wod
                                       Edit.woo
                                   Images
                                       Icon.gif
                                       Background.jpeg
                                   Main.wo
                                       Main.html
                                       Main.wod
                                       Main.woo
 

Then, these resources will appear on the file system as:

                               Resources
                                   Edit.wo
                                       Edit.html
                                       Edit.wod
                                       Edit.woo
                                   Images
                                       Icon.gif
                                       Background.jpeg
                                   Main.wo
                                       Main.html
                                       Main.wod
                                       Main.woo
                                   English.lproj
                                       Edit.wo
                                           Edit.html
                                           Edit.wod
                                           Edit.woo
 

Determining Available Resources

NSBundle provides two methods to determine the resources it contains: resourcePathsForResources and resourcePathsForLocalizedResources. These methods return resource paths, or paths specified according to NSBundle's resource organization, not the physical resource organization as it appears on the file system. For example, the resource path to the Background.jpeg resource in above example is Nonlocalized.lproj/Images/Background.jpeg.

Accessing NSBundle Resources

NSBundle provides two methods to access resources: bytesForResourcePath and inputStreamForResourcePath. Both methods require a single argument: a full resource path as returned by the resourcePathsForResources and resourcePathsForLocalizedResources methods. The bytesForResourcePath method returns a byte array containing data for the resource specified by the path. The inputStreamForResourcePath returns an java.io.InputStream for the resource specified by the path.

Sometimes you want to access a localized resource without specifying the full resource path. For example, if you might want to get the Icon.gif resource appropriate for the current locale. To do this, you invoke resourcePathForLocalizedResourceNamed to determine the full resource path for the localized resource and, in turn, invoke bytesForResourcePath or inputStreamForResourcePath with the full path.

principalClass

public Class principalClass()

Gets the NSBundle's principal class, which is responsible for ensuring that all classes in the framework are properly initialized. The NSBundle determines its principal class based on the bundle's property list. The property list represents a dictionary; the principle class is the value obtained using the key NSPrincipalClass. If the principal class is not specified in the property list, the method returns null. If you create a framework that needs to be initialized using a principal class, you must specify the class name in the CustomInfo.plist file, a source file for the bundle's property list. For example, if your principal class is myPackage.myPrincipalClass, your CustomInfo.plist file should look like:

 {
        NSPrincipalClass = myPackage.myPrincipalClass;
 }
 

Returns:

the NSBundle's principal class

properties

public Properties properties()

Get the properties that are located in the Properties file in the Resources subdirectory of the directory corresponding to this NSBundle.

Returns:

the properties found in the Properties file

resourcePath

@Deprecated
public String resourcePath()

Returns:

See Also:

NSBundle.bytesForResourcePath(String), NSBundle.inputStreamForResourcePath(String)

resourcePathForLocalizedResourceNamed

public String resourcePathForLocalizedResourceNamed(String aName,
                                                    String aSubDirPath)

Determines the resource path of the resource named aName based on the current locale. This method first searches the current locale's language directory for the resource then the Nonlocalized.lproj directory. If it finds the resource, it returns the resource's path. Otherwise it returns null. You can specify a subdirectory aSubDirPath for the method to search in. For example, if the current locale is English, and the resources are organized as shown in the class description and you invoke resourcePathForLocalizedResourceNamed for the "Edit.html" resource in the "Edit.wo" subdirectory, the method returns "English.lproj/Edit.wo/Edit.html". If the current locale is German, the method returns "Nonlocalized.lproj/Edit.wo/Edit.html".

Parameters:

aName - the name of the resource

aSubDirPath - the subdirectory where it is searched; if it is null, the method returns a resource path for a localized resource at the language directory level.

Returns:

resource path for the localized resource with the specified name

public NSArray resourcePathsForDirectories(String extension,
                                           String aSubDirPath)

Gets an array containing the resource paths of all the directories with the specified extension anExtension beneath the specified subdirectory aSubDirPath. If anExtension is null, the method includes directories regardless of extension. If aSubDirPath is null, the method returns directories beneath the top level directory (the one containing the language directories).

Examples of invoking resourcePathsForDirectories with various parameters for the bundle depicted in the class description.

resourcePathsForLocalizedResources

public NSArray resourcePathsForLocalizedResources(String extension,
                                                  String aSubDirPath)

Gets an array containing the resource paths for all of the receiver's resources that are appropriate for the current locale, have the specified file extension anExtension, and lie within the specified subdirectory aSubDirPath.

If a resource appears in more than one language directory, this method chooses whether to include it in the array based on the following criteria:

• If the resource appears in the language directory for the current locale, the method includes its path in the results array.
• If the resource appears in Nonlocalized.lproj but not in the current locale's language directory, the method includes its path in the results array.
• If the resource doesn't appear in Nonlocalized.lproj or the current locale's language directory the method does not include its path in the results array.

This method also takes the extension and subdirectory arguments that allow you to filter the result array based on the extension or subdirectory. Examples of invoking this method with various parameters for the bundle depicted in the class description.
