Example 1 with ResourceStorageProviderAdapter

use of org.eclipse.xtext.resource.persistence.ResourceStorageProviderAdapter in project xtext-core by eclipse.

the class ResourceStorageFacade method getOrCreateResourceStorageLoadable.

 * Clients should first call shouldLoadFromStorage to check whether there exists a storage version
 * of the given resource.
 *
 * @return an IResourceStorageLoadable
