                             org.eclipse.core.runtime.IProgressMonitor monitor)

getCopiedResourceDescriptionsData

protected ResourceDescriptionsData getCopiedResourceDescriptionsData()

getAllResourceDescriptions

public java.lang.Iterable<IResourceDescription> getAllResourceDescriptions()

Specified by:

getAllResourceDescriptions in interface IResourceDescriptions

getResourceDescription

public IResourceDescription getResourceDescription(org.eclipse.emf.common.util.URI uri)

Description copied from interface: IResourceDescriptions

Returns the resource descriptions for the given URI. It's the client's responsibility to normalize the URI.

Specified by:

getResourceDescription in interface IResourceDescriptions

setPersister

public void setPersister(PersistedStateProvider persister)

update

public com.google.common.collect.ImmutableList<IResourceDescription.Delta> update(BuildData buildData,
                                                                                  org.eclipse.core.runtime.IProgressMonitor monitor)

Description copied from interface: IBuilderState

Updated the underlying IResourceDescriptions according to the passed URIs. It updates transitively affected IResourceDescription as well. The change to the underlying IResourceDescriptions is guaranteed to be atomic.

Specified by:

update in interface IBuilderState

Parameters:

buildData - the underlying data for the update.

monitor - the progress monitor to use for reporting progress to the user. It is the caller's responsibility to call done() on the given monitor. Accepts null, indicating that no progress should be reported and that the operation cannot be canceled.

Returns:

a list of changes in the form of deltas.

doUpdate

protected abstract java.util.Collection<IResourceDescription.Delta> doUpdate(BuildData buildData,
                                                                             ResourceDescriptionsData newData,
                                                                             org.eclipse.core.runtime.IProgressMonitor monitor)

clean

public com.google.common.collect.ImmutableList<IResourceDescription.Delta> clean(java.util.Set<org.eclipse.emf.common.util.URI> toBeRemoved,
                                                                                 org.eclipse.core.runtime.IProgressMonitor monitor)

Description copied from interface: IBuilderState

Remove the descriptions for the given resource-uris from the IResourceDescriptions. The clean-operation is not transitive. The change to the underlying IResourceDescriptions is guaranteed to be atomic.

Specified by:

clean in interface IBuilderState

Parameters:

toBeRemoved - the uris or the cleaned resources.

monitor - the progress monitor to use for reporting progress to the user. It is the caller's responsibility to call done() on the given monitor. Accepts null, indicating that no progress should be reported and that the operation cannot be canceled.

Returns:

a list of changes in the form of deltas.

doClean

protected java.util.Collection<IResourceDescription.Delta> doClean(java.util.Set<org.eclipse.emf.common.util.URI> toBeRemoved,
                                                                   org.eclipse.core.runtime.IProgressMonitor monitor)

getExportedObjects

public java.lang.Iterable<IEObjectDescription> getExportedObjects()

Specified by:

getExportedObjects in interface ISelectable

Returns:

all exported elements. May not be null.

getExportedObjects

public java.lang.Iterable<IEObjectDescription> getExportedObjects(org.eclipse.emf.ecore.EClass type,
                                                                  QualifiedName name,
                                                                  boolean ignoreCase)

Specified by:

getExportedObjects in interface ISelectable

Returns:

all elements which match the given qualified name and type. May not be null.

getExportedObjectsByType

public java.lang.Iterable<IEObjectDescription> getExportedObjectsByType(org.eclipse.emf.ecore.EClass type)

Specified by:

getExportedObjectsByType in interface ISelectable

Returns:

all elements which match the given type. May not be null.

getExportedObjectsByObject

public java.lang.Iterable<IEObjectDescription> getExportedObjectsByObject(org.eclipse.emf.ecore.EObject object)

Specified by:

getExportedObjectsByObject in interface ISelectable

Returns:

all elements which match the given instance. May not be null.

isEmpty

public boolean isEmpty()

Description copied from interface: ISelectable

Clients may want to check the selectable to skip its processing in case it is empty. Implementations should be fast and not require expensive precalculation. Selectable may return false if it is too expensive to compute the actual result.

Specified by:

isEmpty in interface ISelectable

Returns:

true if the selectable does not provide any descriptions.
