Method Detail

loadStringResource

public String loadStringResource(Component component,
                                 String key,
                                 Locale locale,
                                 String style,
                                 String variation)

Description copied from interface: IStringResourceLoader

Get the string resource for the given combination of component, resource key, locale and style. The component provided is used to allow implementation of component specific resource loading (e.g. per page or per reusable component). The key should be a String containing a lookup key into a resource bundle. The Locale and the style will be taken from the Component provided.

Specified by:

loadStringResource in interface IStringResourceLoader

Parameters:

component - The component to get the string resource for

key - The key should be a String containing a lookup key into a resource bundle

locale - Will be preset with the appropriate value. You shall ignore the component's locale.

style - Will be preset with the appropriate value. You shall ignore the component's style.

variation - Will be preset with the appropriate value. You shall ignore the component's variation.

Returns:

The string resource value or null if the resource could not be loaded by this loader

loadStringResource

public String loadStringResource(Class<?> clazz,
                                 String key,
                                 Locale locale,
                                 String style,
                                 String variation)

Description copied from interface: IStringResourceLoader

Get the string resource for the given combination of component class, resource key, locale and style. The component class provided is used to allow implementation of component specific resource loading (e.g. per page or per reusable component). The key should be a String containing a lookup key into a resource bundle. The locale should contain the locale of the current operation so that the appropriate set of resources can be selected. The style allows the set of resources to select to be varied by skin/brand.

Specified by:

loadStringResource in interface IStringResourceLoader

Parameters:

clazz - The class to get the string resource for

key - The key should be a String containing a lookup key into a resource bundle

locale - The locale should contain the locale of the current operation so that the appropriate set of resources can be selected

style - The style identifying the resource set to select the strings from (see Session)

variation - The components variation (of the style)

Returns:

The string resource value or null if the resource could not be loaded by this loader
