Examples with UploadProjectSuccessPayload org.eclipse.sirius.web.services.api.projects.UploadProjectSuccessPayload used on opensource projects

Example 1 with UploadProjectSuccessPayload

use of org.eclipse.sirius.web.services.api.projects.UploadProjectSuccessPayload in project sirius-web by eclipse-sirius.

the class ProjectImportService method importProject.

/**
 * Returns {@link UploadProjectSuccessPayload} if the project import has been successful, {@link ErrorPayload}
 * otherwise.
 *
 * <p>
 * Unzip the given {@link UploadFile}, then creates a project with the name of the root directory in the zip file,
 * then use {@link ProjectImporter} to create documents and representations. If the project has not been imported,
 * it disposes the {@link IEditingContextEventProcessor} used to create documents and representations then delete
 * the created project in order to keep the server in the same state before the project upload attempt.
 * </p>
 *
 * @param inputId
 *            The identifier of the input which has triggered the upload
 * @param file
 *            the file to upload
 * @return {@link UploadProjectSuccessPayload} whether the project import has been successful, {@link ErrorPayload}
 *         otherwise
