Class AbstractLocaleDAOImpl

java.lang.Object

org.alfresco.repo.domain.locale.AbstractLocaleDAOImpl

All Implemented Interfaces:

LocaleDAO

Direct Known Subclasses:

LocaleDAOImpl

public abstract class AbstractLocaleDAOImpl
extends Object
implements LocaleDAO

Abstract implementation for Locale DAO.

This provides basic services such as caching, but defers to the underlying implementation for CRUD operations. Since locales are system-wide and immutable, we can cache lookups in both directions.

Constructor Detail

AbstractLocaleDAOImpl

protected AbstractLocaleDAOImpl()

Default constructor.

This sets up the DAO accessors to bypass any caching to handle the case where the caches are not supplied in the setters.

Method Detail

setLocaleEntityCache

public void setLocaleEntityCache(org.alfresco.repo.cache.SimpleCache<Long,String> localeEntityCache)

Set the cache that maintains the ID-Locale mappings and vice-versa (bi-directional)

Parameters:

localeEntityCache - the cache

getLocalePair

public org.alfresco.util.Pair<Long,Locale> getLocalePair(Locale locale)

Specified by:

getLocalePair in interface LocaleDAO

Returns:

the locale or null if no such locale exists

getDefaultLocalePair

public org.alfresco.util.Pair<Long,Locale> getDefaultLocalePair()

Specified by:

getDefaultLocalePair in interface LocaleDAO

Returns:

the locale pair for the default locale. Although the Locale object will be populated, the ID will point to an instance that generically refers to the system's default locale i.e. the value returned can vary depending on the executing thread's default locale.

getLocalePair

public org.alfresco.util.Pair<Long,Locale> getLocalePair(Long id)

Specified by:

getLocalePair in interface LocaleDAO

Parameters:

id - the unique ID of the entity

Returns:

the locale pair (never null)

getOrCreateLocalePair

public org.alfresco.util.Pair<Long,Locale> getOrCreateLocalePair(Locale locale)

Gets the locale ID for an existing instance or creates a new entity if one doesn't exist.

Specified by:

getOrCreateLocalePair in interface LocaleDAO

Parameters:

locale - the locale to fetch or null to get or create the default locale.

Returns:

the locale - never null

getOrCreateDefaultLocalePair

public org.alfresco.util.Pair<Long,Locale> getOrCreateDefaultLocalePair()

Find or create the details representing the default locale.

Specified by:

getOrCreateDefaultLocalePair in interface LocaleDAO

Returns:

the locale pair for the default locale. Although the Locale object will be populated, the ID will point to an instance that generically refers to the system's default locale i.e. the value returned can vary depending on the executing thread's default locale.

getLocaleEntity

protected abstract LocaleEntity getLocaleEntity(Long id)
