openCMIS: path of cmis object

Document (or) folder can be identified by absolute path. Below are the rules in constructing paths.

a.   Root folder has the path ‘/’.

b.   All the paths must start with root folder ‘/’.

c.    If folder A is under the root, and folder B is under A, then the path would be /A/B.

How to get an object by path

Session interface provides 'getObjectByPath' method to get the cmis object by using path.

Session session = getSession();

CmisObject cmisObject = session.getObjectByPath("/My_Folder-0-0");

Below is the complete working application.

TestCmis.java

package com.sample.util;

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import org.apache.chemistry.opencmis.client.api.CmisObject;
import org.apache.chemistry.opencmis.client.api.Session;
import org.apache.chemistry.opencmis.client.api.SessionFactory;
import org.apache.chemistry.opencmis.client.runtime.SessionFactoryImpl;
import org.apache.chemistry.opencmis.commons.SessionParameter;
import org.apache.chemistry.opencmis.commons.enums.BindingType;

public class TestCmis {

 private static String serverURL = "http://localhost:8080/chemistry-opencmis-server-inmemory-1.1.0/browser";
 private static String repositoryId = "A1";

 private static Session getSession() {
  Map<String, String> parameters = new HashMap<>();
  parameters.put(SessionParameter.BINDING_TYPE, BindingType.BROWSER.value());

  parameters.put(SessionParameter.USER, "");
  parameters.put(SessionParameter.PASSWORD, "");

  parameters.put(SessionParameter.REPOSITORY_ID, repositoryId);
  parameters.put(SessionParameter.BROWSER_URL, serverURL);

  SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
  return sessionFactory.createSession(parameters);
 }

 public static void main(String args[]) throws IOException {

  Session session = getSession();

  CmisObject cmisObject = session.getObjectByPath("/My_Folder-0-0");
  
  System.out.println("Name : " + cmisObject.getName());
  System.out.println("Type : " + cmisObject.getType());
  
 }

}

Output

Every fileable object provides ‘getParents’ method to get all the parents associated with it.

Document document = (Document)session.getObjectByPath("/My_Folder-0-0/My_Folder-1-0/Hello.txt");

List<Folder> folders = document.getParents();
