retrieve

public Object retrieve(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 ConfluenceBandanaContext because that's how Confluence uses Bandana.

Specified by:

retrieve in interface BandanaPersister

retrieve

public Map retrieve(BandanaContext context)

This implementation is extremely processor intensive but correct. The assumption is that this method NEVER gets called.

Specified by:

retrieve in interface BandanaPersister

Parameters:

context - context to retrieve content for.

Returns:

a Map from String key to Object value

retrieveKeys

public Iterable<String> retrieveKeys(BandanaContext bandanaContext)

Bypass the cache

Specified by:

retrieveKeys in interface BandanaPersister

Parameters:

bandanaContext - the context for which to get keys

Returns:

the keys for the given context

store

public void store(BandanaContext context,
                  String key,
                  Object value)

Specified by:

store in interface BandanaPersister

flushCaches

public void flushCaches()

Specified by:

flushCaches in interface BandanaPersister

remove

public void remove(BandanaContext context)

Specified by:

remove in interface BandanaPersister
