Method Detail

getRepository

InternalRepository getRepository()

This method returns the repository this project is shared on.

Specified by:

getRepository in interface ECPRepositoryAware

Returns:

the repository of this project or null if not shared

getProvider

InternalProvider getProvider()

This method returns the provider of this project.

Specified by:

getProvider in interface ECPProviderAware

Returns:

the provider of this project

getProviderSpecificData

Object getProviderSpecificData()

This method returns the provider specific data of this project.

Returns:

the provider specific data of this project

setProviderSpecificData

void setProviderSpecificData(Object data)

This method sets the provider specific data of this project.

Parameters:

data - the provider specific data of this project

notifyObjectsChanged

void notifyObjectsChanged(Collection<Object> objects,
                          boolean structural)

This method is a callback for the provider to notify the project about changes.

Parameters:

objects - the objects that have changed

structural - if the changes where structural (e.g. delete)

undispose

void undispose(InternalRepository repository)

This method undisposes the project based on a repository.

Parameters:

repository - the repository

notifyProvider

void notifyProvider(InternalProvider.LifecycleEvent event)

This method is used to notify the provider about a InternalProvider.LifecycleEvent of this project.

Parameters:

event - to pass to the provider

clone

InternalProject clone(String name)

This method clones a project.

Parameters:

name - the name of the project to create

Returns:

the cloned project

saveProperties

@Deprecated
void saveProperties()

Deprecated. As of 1.1 properties are saved automatically when they're changed.

Saves the properties, such as visible packages or the name of the project into the workspace.

getReferenceCandidates

Iterator<org.eclipse.emf.ecore.EObject> getReferenceCandidates(org.eclipse.emf.ecore.EObject eObject,
                                                               org.eclipse.emf.ecore.EReference eReference)

Get all possible EObjects from the provider to which a reference can be added from a certain EObject based on the type of the EReference.

Parameters:

eObject - - the EObject for which the reference should be set.

eReference - - the EReference to be set.

Returns:

Iterator over all EObject that can be added as a reference

isModelRoot

boolean isModelRoot(Object object)

This method checks whether the provided object is the model root of the project.
