NodeDAO

All Known Implementing Classes:

AbstractNodeDAOImpl, NodeDAOImpl, NodeDAOImpl.MSSQL, NodeDAOImpl.MySQL, NodeDAOImpl.MySQLClusterNDB

public interface NodeBulkLoader

A component that pre-fetches cached data for the given nodes. Client code can use this component when a list of NodeRef instances will be processed in a data-intensive manner.

Method Summary

Modifier and Type	Method and Description
void	cacheNodes(List<org.alfresco.service.cmr.repository.NodeRef> nodeRefs) Pre-cache data relevant to the given nodes.
void	cacheNodesById(List<Long> nodeIds) Pre-cache data relevant to the given nodes.
void	clear() FOR TESTING ONLY: Clears out node cache data
Set<Long>	getCachedAncestors(List<Long> nodeIds) Gets the current set of cached ancestors of the given list of nodes.
void	setCheckNodeConsistency() Transaction-scope setting to make the Node loader to guarantee the validity of all caches: some cache data will be reloaded; some cache data will be considered safe.

Method Detail

getCachedAncestors

Set<Long> getCachedAncestors(List<Long> nodeIds)

Gets the current set of cached ancestors of the given list of nodes.

Parameters:

nodeIds - a list of node IDs to visit

Returns:

the current set of cached ancestors of the given list of nodes, including the nodes themselves.

setCheckNodeConsistency

void setCheckNodeConsistency()

Transaction-scope setting to make the Node loader to guarantee the validity of all caches: some cache data will be reloaded; some cache data will be considered safe.

cacheNodes

void cacheNodes(List<org.alfresco.service.cmr.repository.NodeRef> nodeRefs)

Pre-cache data relevant to the given nodes. There is no need to split the collection up before calling this method; it is up to the implementations to ensure that batching is done where necessary.

Parameters:

nodeRefs - the nodes that will be cached.

cacheNodesById

void cacheNodesById(List<Long> nodeIds)

Pre-cache data relevant to the given nodes. There is no need to split the collection up before calling this method; it is up to the implementations to ensure that batching is done where necessary.

Parameters:

nodeIds - the nodes that will be cached.

clear

void clear()

FOR TESTING ONLY: Clears out node cache data
