Class WorkspaceCache

java.lang.Object
  org.modeshape.jcr.cache.document.WorkspaceCache

All Implemented Interfaces:

ChangeSetListener, DocumentCache, NodeCache

public class WorkspaceCache
extends Object
implements DocumentCache, ChangeSetListener

A NodeCache implementation that uses Infinispan's SchematicDb for storage, with each node represented as a single Document. The nodes in this cache represent the actual, unmodified values.

Constructor Summary

WorkspaceCache(ExecutionContext context, String repositoryKey, String workspaceName, SchematicDb database, long largeValueSize, NodeKey rootKey, ConcurrentMap<NodeKey,CachedNode> cache, ChangeSetListener changeSetListener)

Method Summary

void	changed(ChangeSet changes) Signal that changes have been made to the persisted data.
protected void	checkNotClosed()
void	clear() Clears all changes in the cache.
Iterator<NodeKey>	getAllNodeKeys() Get an iterator over all node keys within this cache.
Iterator<NodeKey>	getAllNodeKeysAtAndBelow(NodeKey startingKey) Get an iterator over all keys for the supplied node and all its descendants.
CachedNode	getNode(ChildReference reference) Get the cached representation of the node as represented by the supplied child reference.
CachedNode	getNode(NodeKey key) Get the cached representation of the node with the supplied node key.
String	getProcessKey()
String	getRepositoryKey()
NodeKey	getRootKey() Get the node key for the root node.
String	getWorkspaceKey()
String	getWorkspaceName()
void	notify(ChangeSet changeSet)
void	setMinimumBinarySizeInBytes(long largeValueSize)

WorkspaceCache

public WorkspaceCache(ExecutionContext context,
                      String repositoryKey,
                      String workspaceName,
                      SchematicDb database,

Method Detail

setMinimumBinarySizeInBytes

public void setMinimumBinarySizeInBytes(long largeValueSize)

workspaceCache

public final WorkspaceCache workspaceCache()

Specified by:

workspaceCache in interface DocumentCache

getProcessKey

public final String getProcessKey()

getRepositoryKey

public final String getRepositoryKey()

getWorkspaceKey

public final String getWorkspaceKey()

getWorkspaceName

public final String getWorkspaceName()

getRootKey

public NodeKey getRootKey()

Description copied from interface: NodeCache

Get the node key for the root node.

Specified by:

getRootKey in interface NodeCache

Returns:

the root node's key; never null

getNode

public CachedNode getNode(NodeKey key)

Description copied from interface: NodeCache

Get the cached representation of the node with the supplied node key.

Specified by:

getNode in interface NodeCache

Parameters:

key - the node key; may not be null

Returns:

the cached node, or null if there is no such node

getNode

public CachedNode getNode(ChildReference reference)

Description copied from interface: NodeCache

Get the cached representation of the node as represented by the supplied child reference. This is a convenience method that is equivalent to calling:

 getNode(reference.getKey());
 

Specified by:

getNode in interface NodeCache

Parameters:

reference - the child node reference; may not be null

Returns:

the cached node to which the reference points, or null if the child reference no longer points to a valid node

getAllNodeKeys

public Iterator<NodeKey> getAllNodeKeys()

Description copied from interface: NodeCache

Get an iterator over all node keys within this cache. The order of the keys is not defined.

Specified by:

getAllNodeKeys in interface NodeCache

Returns:

an iterator over all the cache's node keys; never null

getAllNodeKeysAtAndBelow

public Iterator<NodeKey> getAllNodeKeysAtAndBelow(NodeKey startingKey)

Description copied from interface: NodeCache

Get an iterator over all keys for the supplied node and all its descendants. The order of the keys is not defined.

Specified by:

getAllNodeKeysAtAndBelow in interface NodeCache

Parameters:

startingKey - the key for the node to start; may not be null

Returns:

an iterator over all the cache's node keys; never null

clear

public void clear()

Description copied from interface: NodeCache

Clears all changes in the cache.

Specified by:

clear in interface NodeCache

notify

public void notify(ChangeSet changeSet)

Specified by:

notify in interface ChangeSetListener

changed

public void changed(ChangeSet changes)

Signal that changes have been made to the persisted data. Related information in the cache is cleared, and this workspace's listener is notified of the changes.

Parameters:

changes - the changes to be made; may not be null

checkNotClosed

protected final void checkNotClosed()

signalDeleted

public void signalDeleted()

signalClosing

public void signalClosing()

signalClosed

public void signalClosed()

toString

public String toString()

Overrides:

toString in class Object
