Class DLStoreUtil

java.lang.Object
  com.liferay.portlet.documentlibrary.store.DLStoreUtil

public class DLStoreUtil
extends Object

Provides methods for storing files in the portal. The file storage implementation can be selected in portal.properties under the property dl.store.impl. Virus checking can also be enabled under the property dl.store.antivirus.impl.

The main client for this class is the Document Library portlet. It is also used by other portlets like Wiki and Message Boards to store file attachments. For the Document Library portlet, the repositoryId can be obtained by calling DLFolderConstants.getDataRepositoryId( long,long). For all other portlets, the repositoryId should be set to CompanyConstants#SYSTEM. These methods can be used in plugins and other portlets, as shown below.

 
 long repositoryId = CompanyConstants.SYSTEM;
 String dirName = "portlet_name/1234";

 try {
 DLStoreUtil.addDirectory(companyId, repositoryId, dirName);
 }
 catch (DuplicateDirectoryException dde) {
 }

 DLStoreUtil.addFile(
 companyId, repositoryId, dirName + "/" + fileName, file);
