Public Constructors

public NoopPersistenceManager ()

Public Methods

public void applyUserWriteToServerCache (Path path, Node node)

Parameters

path
node

public void applyUserWriteToServerCache (Path path, CompoundWrite merge)

Parameters

path
merge

public List<UserWriteRecord> loadUserWrites ()

Return a list of all writes that were persisted

Returns

The list of writes

public void removeAllUserWrites ()

Removes all writes

public void removeUserWrite (long writeId)

Remove a write with the given write id.

Parameters

writeId	The write id to remove

public T runInTransaction (Callable<T> callable)

Parameters

callable

public void saveUserMerge (Path path, CompoundWrite children, long writeId)

Save a user merge

Parameters

path	The path for this merge
children	The children for this merge
writeId	The write id that was used for this merge

public void saveUserOverwrite (Path path, Node node, long writeId)

Save a user overwrite

Parameters

path	The path for this write
node	The node for this write
writeId	The write id that was used for this write

public CacheNode serverCache (QuerySpec query)

Returns any cached node or children as a CacheNode. The query is *not* used to filter the node but rather to determine if it can be considered complete.

Parameters

query	The query at the path

Returns

The cached node or an empty CacheNode if no cache is available

public void setQueryActive (QuerySpec query)

Parameters

query

public void setQueryComplete (QuerySpec query)

Parameters

query

public void setQueryInactive (QuerySpec query)

Parameters

query

public void setTrackedQueryKeys (QuerySpec query, Set<ChildKey> keys)

Parameters

query
keys

public void updateServerCache (QuerySpec query, Node node)

Overwrite the server cache with the given node for a given query. The query is considered to be complete after saving this node.

Parameters

query	The query for which to apply this overwrite.
node	The node to replace in the cache at the given path

public void updateServerCache (Path path, CompoundWrite children)

Update the server cache at the given path with the given merge.

NOTE: This doesn't mark any queries complete, since the common case is that there's already a complete query above this location.

Parameters

path	The path for this merge
children	The children to update

public void updateTrackedQueryKeys (QuerySpec query, Set<ChildKey> added, Set<ChildKey> removed)

Parameters

query
added
removed
