IContainer (org.eclipse.xtext 2.30.0 API)

All Superinterfaces:

ISelectable

All Known Implementing Classes:

AbstractContainer, DescriptionAddingContainer, FilterUriContainer, LiveShadowedChunkedContainer, ResourceDescriptionsBasedContainer, StateBasedContainer
```
public interface IContainer
extends ISelectable
```
A container describes resources that should be treated as visible on the same level during the scoping stage. This depends on language implementations in a way that a container that was obtained for a given resource may contain other resources that would create other containers with distinct contents. A container may be optimized by means of the ISelectable-contract.

- Method Detail
  - getResourceDescriptions
```
java.lang.Iterable<IResourceDescription> getResourceDescriptions()
```
    Returns:
    
    the IResourceDescription contained in this container. The result is never null. The result may be a cached view on the actual content of the underlying resources.
  - getResourceDescriptionCount
```
int getResourceDescriptionCount()
```
    Returns:
    
    the total number of resource descriptions returned by getResourceDescriptions()
  - hasResourceDescription
```
boolean hasResourceDescription(org.eclipse.emf.common.util.URI uri)
```
    Returns:
    
    true if the container can provide a resource description with the given uri.
  - getResourceDescription
```
IResourceDescription getResourceDescription(org.eclipse.emf.common.util.URI uri)
```
    Returns:
    
    the IResourceDescription for the given URI, or null is this container does not contain such an IResourceDescription. The result may be a cached view on the actual content of the underlying resource.
