Package org.apache.wicket.core.util.resource.locator

Class ResourceNameIterator

java.lang.Object

org.apache.wicket.core.util.resource.locator.ResourceNameIterator

All Implemented Interfaces:

Iterator<String>, IResourceNameIterator

Direct Known Subclasses:

EmptyResourceNameIterator

public class ResourceNameIterator
extends Object
implements IResourceNameIterator

Contains the logic to locate a resource based on a path, style (see Session), variation, locale and extension strings. The full filename will be built like: <path>_<variation>_<_<style>_<locale>.<extension>.

Resource matches will be attempted in the following order:

1. 1. <path>_<style>_<locale>.<extension>
2. 2. <path>_<locale>.<extension>
3. 3. <path>_<style>.<extension>
4. 4. <path>.<extension>

Locales may contain a language, a country and a region or variant. Combinations of these components will be attempted in the following order:

1. locale.toString() see javadoc for Locale for more details
2. <language>_<country>
3. <language>

Constructor Detail

ResourceNameIterator

public ResourceNameIterator(String path,
                            String style,
                            String variation,
                            Locale locale,
                            Iterable<String> extensions,
                            boolean strict)

Construct.

Parameters:

path - The path of the resource. In case the parameter 'extensions' is null, the path will be checked and if a filename extension is present, it'll be used instead.

style - A theme or style (see Session)

variation - The component's variation (of the style)

locale - The Locale to apply

extensions - the filename's extensions

strict - If false, weaker combinations of style, locale, etc. are tested as well
