Method Detail

getMessage

public Message getMessage(String namespace,
                          String component,
                          String key,
                          String locale)

Iterates through the resource bundles for the give namespace (or the application if namespace is not given) and finds the message that matches the given key

If the message is found in more than one bundle, the text from the bundle that is loaded last will be used

If the given component code is the default component, resource keys that do not have a component defined and match the given key will also be considered matches

Specified by:

getMessage in interface MessageProvider

Parameters:

namespace - namespace code the message belongs to

component - component code the namespace is associated with

key - key that identifies the message within the namespace and component

locale - locale code for the message to return

Returns:

Message matching message object, or null if a message was not found

See Also:

MessageProvider.getMessage(java.lang.String, java.lang.String, java.lang.String, java.lang.String)

getAllMessagesForComponent

public Collection<Message> getAllMessagesForComponent(String namespace,
                                                      String component,
                                                      String locale)

Iterates through the resource bundles for the give namespace (or the application if namespace is not given) and finds all messages that match the given namespace

If the same resource key is found in more than one bundle, the text from the bundle that is loaded last will be used

If the given component code is the default component, resource keys that do not have a component defined and match the given key will also be considered matches

Specified by:

getAllMessagesForComponent in interface MessageProvider

Parameters:

namespace - namespace code the message belongs to

component - component code the namespace is associated with

locale - locale code for the message to return

Returns:

Collection collection of messages that match, or empty collection if no messages are found

See Also:

MessageProvider.getAllMessagesForComponent(java.lang.String, java.lang.String, java.lang.String)

cleanResourceKey

protected String cleanResourceKey(String resourceKey)

Removes any component declaration within the given resource key

Parameters:

resourceKey - resource key to clean

Returns:

String cleaned resource key

                               String key,
                               String messageText,
                               String locale)
