Method Detail

create

public static ReadThroughCachingBandanaPersister create(com.atlassian.bandana.BandanaPersister persister,
                                                        com.atlassian.cache.CacheFactory cacheFactory)

retrieve

public @Nullable Object retrieve(com.atlassian.bandana.BandanaContext context,
                                 String key)

Retrieves the value associated with the key from the given context. If the context does not exist, or the key is not found in the context, this method returns null.

Assumes that any BandanaContext we are passed is a KeyedBandanaContext because that's how Confluence uses Bandana.

Specified by:

retrieve in interface com.atlassian.bandana.BandanaPersister

retrieve

public Map<String,Object> retrieve(com.atlassian.bandana.BandanaContext context)
