DEVSPEED-34: We wanted to properly cache the I18nBean. To make that happen we turned the I18nBean into a flyweight during JIRA 4.3. All of the original logic was moved into this class.

Looking up translations in plugins happens lazily. This (shouldn't) have any real world impact but it makes certain unit tests easier. (You don't need to worry about mocking out PluginAccessor.)

Note that this class is cached by the I18nBean.CachingFactory per Locale and will be re-created during plugin reload events.

Since:
4.3

BackingI18n

public BackingI18n(Locale locale,
                   I18nTranslationMode i18nTranslationMode,

Construct an I18nBean in the given Locale.

Parameters:
locale - the Locale
i18nTranslationMode - whether the magic translate mode is on or not
involvedPluginsTracker - keeps track of which plugins have I18N information so that we can avoid flushing the translation cache when unrelated modules

Method Detail

getLocale

public Locale getLocale()
Specified by:
getLocale in interface I18nHelper
Returns:
the Locale that is associated with this I18nHelper

getDefaultResourceBundle

public ResourceBundle getDefaultResourceBundle()
Description copied from interface: I18nHelper
Returns the default ResourceBundle within JIRA, which does not include translations provided by plugins. For use cases where non-English translations are required, call I18nHelper.getResourceBundle() instead.

Specified by:
getDefaultResourceBundle in interface I18nHelper
Returns:
a non-null bundle
See Also:
I18nHelper.getResourceBundle()

getPluginAccessor

protected com.atlassian.plugin.PluginAccessor getPluginAccessor()
Subclasses should override this and return null if they don't want to touch the ComponentManager

Returns:
a PluginAccessor if its null then plugin resource loading wont happen

getKeysForPrefix

public Set<String> getKeysForPrefix(String prefix)
Description copied from interface: I18nHelper
Given a prefix for an i18n key, this method will return all keys that start with the prefix specified.

Specified by:
getKeysForPrefix in interface I18nHelper
Parameters:
prefix - The prefix for i18n keys. May not be null
Returns:
An immutable set of translation keys that start with the prefix specified.

getUnescapedText

public String getUnescapedText(String key)
Get the raw property value, complete with {0}'s.

Specified by:
getUnescapedText in interface I18nHelper
Parameters:
key - Non-null key to look up
Returns:
Unescaped property value for the key, or the key itself if no property with the specified key is found

getUntransformedRawText

public String getUntransformedRawText(String key)
Description copied from interface: I18nHelper
Same as I18nHelper.getUnescapedText(String) but does not apply any TranslationTransforms.

Specified by:
getUntransformedRawText in interface I18nHelper
Parameters:
key - the key of the i18n message
Returns:
the un-formatted text or the key itself if no i18n message can be found

isKeyDefined

public boolean isKeyDefined(String key)
Description copied from interface: I18nHelper

For the given key, checks whether such a key is defined in the locale context represented by this helper instance. Note that the actual translation may be in the 'fallback' default locale rather than the current locale.

The contract of this is method is correlated with I18nHelper.getUntransformedRawText(String), whereby if this method returns false, I18nHelper.getUntransformedRawText(String) will return the key provided as an argument, and if this method returns true, I18nHelper.getUntransformedRawText(String) will generally return the translation, which in some very unlikely cases may be equal to the key.

Specified by:
isKeyDefined in interface I18nHelper
Parameters:
key - translation key
Returns:
true, if any translation for such key exists, false otherwise
