Interface ComponentMessagesSource

All Known Implementing Classes:

ComponentMessagesSourceImpl

@UsesOrderedConfiguration(value=Resource.class)
public interface ComponentMessagesSource

Used to connect a Tapestry component to its message catalog, or to obtain the application catalog (that all component message catalogs extend from). The application catalog is defined by the collection of Resources contributed to the service. In general, component libraries will contribute a Resource before the "AppCatalog" resource (representing the application message catalog, WEB-INF/app.properties) so that the application can override messages of the component library.

Method Summary

Messages	getApplicationCatalog(Locale locale) Gets the Messages derived from the application's message catalog.
InvalidationEventHub	getInvalidationEventHub() Returns the event hub that allows listeners to be notified when any underlying message catalog file is changed.
Messages	getMessages(ComponentModel componentModel, ComponentResourceSelector selector) Used to obtain a Messages instance for a particular component, using a particular selector.
Messages	getMessages(ComponentModel componentModel, Locale locale) Deprecated. Deprecated in 5.3; use getMessages(ComponentModel, ComponentResourceSelector) instead.

Method Detail

getMessages

Messages getMessages(ComponentModel componentModel,
                     Locale locale)

Deprecated. Deprecated in 5.3; use getMessages(ComponentModel, ComponentResourceSelector) instead.

Used to obtain a Messages instance for a particular component, within a particular locale. If the component extends from another component, then its localized properties will merge with its parent's properties (with the subclass overriding the super class on any conflicts).

Parameters:

componentModel -

locale -

Returns:

the message catalog for the component, in the indicated locale

getMessages

Messages getMessages(ComponentModel componentModel,
                     ComponentResourceSelector selector)

Used to obtain a Messages instance for a particular component, using a particular selector. If the component extends from another component, then its localized properties will merge with its parent's properties (with the subclass overriding the super class on any conflicts).

Parameters:

componentModel -

selector - determined correct version of messages to obtain

Returns:

the message catalog for the component, in the indicated selector
