Example 41 with IResourceDescriptions

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

the class ResourceDescriptionsProvider method getResourceDescriptions.

/**
 * Provides the proper resource descriptions according to the context in which the resource set is used.
 *
 * The context is indicated by the {@link ResourceSet#getLoadOptions() load options} of the resource set. Supported
 * options are:
 *
 * <ol>
 * <li>{@link #NAMED_BUILDER_SCOPE}</li>
 * <li>{@link #LIVE_SCOPE}</li>
 * <li>{@link #PERSISTED_DESCRIPTIONS}</li>
 * <li>If no such option is present the dirty editors are taken into account to contribute their contents to the
 * index</li>
 * </ol>
 *
 * The result is never <code>null</code>.
 *
 * @param resourceSet
 *            the resource set that is currently used.
 * @return the {@link IResourceDescriptions} according to the usage context.
