All Implemented Interfaces:

java.io.Serializable, IRequestListener, IResourceListener

Direct Known Subclasses:

CompressedPackageResource

public class PackageResource
extends WebResource

Represents a localizable static resource.

Use like eg:

 PackageResource IMG_UNKNOWN = PackageResource.get(EditPage.class, "questionmark.gif");
 

where the static resource references image 'questionmark.gif' from the the package that EditPage is in to get a package resource.

                          java.lang.String path,
                          java.util.Locale locale,
                          java.lang.String style)

Hidden constructor.

Parameters:

scope - This argument will be used to get the class loader for loading the package resource, and to determine what package it is in

path - The path to the resource

locale - The locale of the resource

style - The style of the resource

Method Detail

bind

public static void bind(Application application,
                        java.lang.Class scope,
                        java.util.regex.Pattern pattern)

Deprecated. Since Wicket 1.2.1 this method is effectively a no-op. package resources are automatically tried and bound as shared resources so that they don't have to be pre-registered anymore. Will be removed in 2.0

Binds the resources that match the provided pattern to the given application object. Will create any resources if not already in the shared resources of the application object.

Parameters:

application - The application to bind to.

scope - The scope of the resource.

pattern - A regular expression to match against the contents of the package of the provided scope class (eg ".\*\.js" will add all the files with extension "js" from that package).

bind

public static void bind(Application application,
                        java.lang.Class scope,

                        boolean recurse)

Deprecated. Since Wicket 1.2.1 this method is effectively a no-op. package resources are automatically tried and bound as shared resources so that they don't have to be pre-registered anymore. Will be removed in 2.0

Binds the resources that match the provided pattern to the given application object. Will create any resources if not already in the shared resources of the application object and does that recursively when the recurse parameter is true, or just for the scoped package if that parameter is false

Parameters:

application - The application to bind to.

scope - The scope of the resource.

pattern - A regular expression to match against the contents of the package of the provided scope class (eg ".\*\.js" will add all the files with extension "js" from that package).

recurse - Whether this method should recurse into sub packages

Parameters:

application - The application to bind to.

scope - The scope of the resource.

name - The name of the resource (like "myfile.js")
