Class TransactionWorkspaceImpl<K,V>

java.lang.Object
  org.jboss.cache.optimistic.TransactionWorkspaceImpl<K,V>

All Implemented Interfaces:

TransactionWorkspace<K,V>

public class TransactionWorkspaceImpl<K,V>
extends Object
implements TransactionWorkspace<K,V>

Contains a mapping of Fqn to WorkspaceNodes. Each entry corresponds to a series of changed nodes within the transaction.

Constructor Summary

TransactionWorkspaceImpl()

Method Summary

void	addNode(WorkspaceNode<K,V> node) Is thread safe so you dont need to deal with synchronising access to this method.
void	clearNodes() Empties the collection of nodes held by this workspace.
WorkspaceNode<K,V>	getNode(Fqn fqn)
Map<Fqn,WorkspaceNode<K,V>>	getNodes() Returns the nodes.
SortedMap<Fqn,WorkspaceNode<K,V>>	getNodesAfter(Fqn fqn) Returns all nodes equal to or after the given node.
boolean	hasNode(Fqn fqn) returns true if the workspace contains a node with specified Fqn
boolean	isVersioningImplicit() Tests if versioning is implicit for a given tx.
WorkspaceNode<K,V>	removeNode(Fqn fqn) Is thread safe so you dont need to deal with synchronising access to this method.
void	setNodes(Map<Fqn,WorkspaceNode<K,V>> nodes) Sets the nodes.
void	setVersioningImplicit(boolean versioningImplicit) Sets if versioning is implicit for a given tx.
String	toString() Returns debug information.

TransactionWorkspaceImpl

public TransactionWorkspaceImpl()

Method Detail

getNodes

public Map<Fqn,WorkspaceNode<K,V>> getNodes()

Returns the nodes.

Specified by:

getNodes in interface TransactionWorkspace<K,V>

Returns:

Returns a map of WorkspaceNodes, keyed on Fqn

clearNodes

public void clearNodes()

Description copied from interface: TransactionWorkspace

Empties the collection of nodes held by this workspace.

Specified by:

clearNodes in interface TransactionWorkspace<K,V>

setNodes

public void setNodes(Map<Fqn,WorkspaceNode<K,V>> nodes)

Sets the nodes.

Specified by:

setNodes in interface TransactionWorkspace<K,V>

Parameters:

nodes - The nodes to set. Takes WorkspaceNodes.

getNode

public WorkspaceNode<K,V> getNode(Fqn fqn)

Specified by:

getNode in interface TransactionWorkspace<K,V>

addNode

public void addNode(WorkspaceNode<K,V> node)

Description copied from interface: TransactionWorkspace

Is thread safe so you dont need to deal with synchronising access to this method.

Specified by:

addNode in interface TransactionWorkspace<K,V>

removeNode

public WorkspaceNode<K,V> removeNode(Fqn fqn)

Description copied from interface: TransactionWorkspace

Is thread safe so you dont need to deal with synchronising access to this method.

Specified by:

removeNode in interface TransactionWorkspace<K,V>

getNodesAfter

public SortedMap<Fqn,WorkspaceNode<K,V>> getNodesAfter(Fqn fqn)

Description copied from interface: TransactionWorkspace

Returns all nodes equal to or after the given node.

Specified by:

getNodesAfter in interface TransactionWorkspace<K,V>

isVersioningImplicit

public boolean isVersioningImplicit()

Description copied from interface: TransactionWorkspace

Tests if versioning is implicit for a given tx. If set to true, the interceptor chain will handle versioning (implicit to JBossCache). If set to false, DataVersions will have to come from the caller.

Specified by:

isVersioningImplicit in interface TransactionWorkspace<K,V>

setVersioningImplicit

public void setVersioningImplicit(boolean versioningImplicit)

Description copied from interface: TransactionWorkspace

Sets if versioning is implicit for a given tx. If set to true, the interceptor chain will handle versioning (implicit to JBossCache). If set to false, DataVersions will have to come from the caller.

Specified by:

setVersioningImplicit in interface TransactionWorkspace<K,V>

hasNode

public boolean hasNode(Fqn fqn)

Description copied from interface: TransactionWorkspace

returns true if the workspace contains a node with specified Fqn

Specified by:

hasNode in interface TransactionWorkspace<K,V>

toString

public String toString()

Returns debug information.

Overrides:

toString in class Object
