CMIS: Check whether repository supports ACLS or not

By querying repository capabilities, you can check whether repository supports ACLS or not.

Below snippet is used to check whether repository supports ACLS or not.

                  CapabilityAcl aclCapabilities = session.getRepositoryInfo().getCapabilities().getAclCapability();

                  if (aclCapabilities == null) {

                           System.out.println("Reposiotry do not support acls");

                           return;

                  }

                  System.out.println("Repository supports acls");

Find the below working application

Test.java

import java.util.HashMap;
import java.util.Map;

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;
import org.apache.chemistry.opencmis.commons.enums.CapabilityAcl;

public class Test {

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

 public 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[]) {
  Session session = getSession();
  CapabilityAcl aclCapabilities = session.getRepositoryInfo().getCapabilities().getAclCapability();

  if (aclCapabilities == null) {
   System.out.println("Reposiotry do not support acls");
   return;
  }

  System.out.println("Repository supports acls");
 }
}

Output

Repository supports acls

CapabilityAcl can have one of three values: none, discover, manage.

Below table summarizes the values of CapabilityAcl.

Value	Description
none	No ACL are supported
discover	Repository support discovery of ACLs
manage	Repository support discovery of ACLs and applying ACLs.

                  Session session = getSession();

                  CapabilityAcl aclCapabilities = session.getRepositoryInfo().getCapabilities().getAclCapability();

                  if (aclCapabilities == null) {

                           System.out.println("Reposiotry do not support acls");

                  } else if (aclCapabilities == CapabilityAcl.NONE) {

                           System.out.println("Reposiotry do not support acls");

                  } else if (aclCapabilities == CapabilityAcl.DISCOVER) {

                           System.out.println("Repository support discovery of ACLs");

                  } else {

                           System.out.println("Repository support discovery of ACLs and applying ACLs.");

                  }

Checking ACL capabilities using workbench

You can check repository ACl capabilities using workbench. Connect to the repository.

Click on the button, Repository Info

Go to Capabilities section, you can able to see whether repository supports capabilities or not.
