Interface IResourceDescription

All Superinterfaces:

ISelectable

All Known Implementing Classes:

AbstractResourceDescription, DefaultResourceDescription, Indexer.ResolvedResourceDescription, SerializableResourceDescription

public interface IResourceDescription
extends ISelectable

A representation of a resource's contents as an ISelectable. The exported objects of a Resource describe its public interface. A description holds information about the imported names which can be used to compute the transitive closure when a resource is modified. Information about the actually established cross references is available, too.

Method Detail

getExportedObjects

Iterable<IEObjectDescription> getExportedObjects()

Specified by:

getExportedObjects in interface ISelectable

Returns:

descriptions of all EObjects provided by the given Resource. The result is expected to return any combination of name and eObjectOrProxy only once as an IEObjectDescription. The order of the exported objects matters.

getImportedNames

Iterable<QualifiedName> getImportedNames()

Returns:

the list of names the described resource depends depends on.

getReferenceDescriptions

Iterable<IReferenceDescription> getReferenceDescriptions()

Returns:

the list of all references contained in the underlying resource.

getURI

org.eclipse.emf.common.util.URI getURI()

Returns:

the uri of the described resource. Will not return null.
