CurrentDescriptions
public CurrentDescriptions(org.eclipse.emf.ecore.resource.ResourceSet resourceSet,
ResourceDescriptionsData newData)
- Create a new index based on an old one.
- Parameters:
resourceSet
- The resource setnewData
- the new index state.
register
public void register(IResourceDescription.Delta delta)
- Put a new resource description into the index, or remove one if the delta has no new description. A delta for a
particular URI may be registered more than once; overwriting any earlier registration.
- Parameters:
delta
- The resource change.
getAllResourceDescriptions
public java.lang.Iterable<IResourceDescription> getAllResourceDescriptions()
- Return the full contents of the index.
- Specified by:
getAllResourceDescriptions
in interface IResourceDescriptions
- Returns:
- The index' contents.
getResourceDescription
public IResourceDescription getResourceDescription(org.eclipse.emf.common.util.URI uri)
- Return the resource description for a URI.
- Specified by:
getResourceDescription
in interface IResourceDescriptions
- Parameters:
uri
- The URI
- Returns:
- The resource description, or null if there is none.
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.
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
.
isAdapterForType
public boolean isAdapterForType(java.lang.Object type)
- Specified by:
isAdapterForType
in interface org.eclipse.emf.common.notify.Adapter
- Overrides:
isAdapterForType
in class org.eclipse.emf.common.notify.impl.AdapterImpl
- Returns:
true
if the given type is class CurrentDescriptions
.
