Class DefaultWorkspaceEditingDomainMapping

java.lang.Object

org.eclipse.sphinx.emf.workspace.domain.mapping.AbstractWorkspaceEditingDomainMapping

org.eclipse.sphinx.emf.workspace.domain.mapping.DefaultWorkspaceEditingDomainMapping

All Implemented Interfaces:

ITransactionalEditingDomainFactoryListener, IWorkspaceEditingDomainMapping

public class DefaultWorkspaceEditingDomainMapping
extends AbstractWorkspaceEditingDomainMapping

Default editing domain mapping. This implementation uses one shared editing domain per type of meta-model on the workspace.

Method Summary

Note In order to retrieve the right editing domain according to the specified meta-model descriptor in a thread safe manner, the access to mappedEditingDomains is synchronized.

Method Detail

createEditingDomain

protected org.eclipse.emf.transaction.TransactionalEditingDomain createEditingDomain(IExtendedTransactionalEditingDomainFactory factory,
                                                                         java.util.Collection<IMetaModelDescriptor> mmDescriptors)

Overrides:

createEditingDomain in class AbstractWorkspaceEditingDomainMapping

getEditingDomain

public org.eclipse.emf.transaction.TransactionalEditingDomain getEditingDomain(org.eclipse.core.resources.IContainer container,
                                                                      IMetaModelDescriptor mmDescriptor)

Note

In order to retrieve the right editing domain according to the specified meta-model descriptor in a thread safe manner, the access to mappedEditingDomains is synchronized. In that way, if two concurrent threads need to get a non-already created editing domain: Both threads won't find any editing domain matching the specified meta-model descriptor; Both will ask for the creation of a new editing domain; Both will try to register this new editing domain into the mappedEditingDomains: One of these two threads first enters the synchronized section. The mappedEditingDomains still do not contain any editing domain for the specified meta-model descriptor; as a consequence it adds it in that map and exits the synchronized section; The second thread enters the synchronized section. As the first thread already registered an editing domain for the specified meta-model descriptor, that second thread just gets that same editing domain instance (in order to finally return it) and exits the synchronized section.

Parameters:

container - The container to use as context object.

mmDescriptor - The meta-model descriptor for which editing domain must be returned.

Returns:

The editing domain associated to the specified meta-model descriptor according to the given context container.

getEditingDomains

public java.util.List<org.eclipse.emf.transaction.TransactionalEditingDomain> getEditingDomains()

Description copied from interface: IWorkspaceEditingDomainMapping

Returns all EditingDomains in the Workspace.

Returns:

The list of TransactionalEditingDomains in the Workspace.

preDisposeEditingDomain

public void preDisposeEditingDomain(org.eclipse.emf.transaction.TransactionalEditingDomain editingDomain)

Description copied from interface: ITransactionalEditingDomainFactoryListener

Notifies clients that an editing domain is about to be disposed.

Specified by:

preDisposeEditingDomain in interface ITransactionalEditingDomainFactoryListener

Overrides:

preDisposeEditingDomain in class AbstractWorkspaceEditingDomainMapping

Parameters:

editingDomain - The editing domain being disposed.

dispose

public void dispose()

Description copied from interface: IWorkspaceEditingDomainMapping

Disposes of this editing domain mapping and any resources that it has allocated. Editing domain mappings must be disposed when they are no longer in use, but only by the client that created them (in case of sharing of editing domain mappings).

Note that editing domain mappings registered on the extension point may not be disposed.

Specified by:

dispose in interface IWorkspaceEditingDomainMapping

Overrides:

dispose in class AbstractWorkspaceEditingDomainMapping
