Cmis: Get object level extensions

Below statements are used to get the extensions associated with cmis object.

Ex

CmisObject cmisObject = session.getObject("134");

List<CmisExtensionElement> extensions = cmisObject.getExtensions(ExtensionLevel.OBJECT);

Find below working application.

Test.java

package cmis_client.cmis_client;

import java.util.HashMap;
import java.util.List;
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.data.CmisExtensionElement;
import org.apache.chemistry.opencmis.commons.enums.BindingType;
import org.apache.chemistry.opencmis.commons.enums.ExtensionLevel;

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);
	}

	private static void printExtensions(List<CmisExtensionElement> extensions, String space) {

		for (CmisExtensionElement extension : extensions) {
			List<CmisExtensionElement> extensionChildren = extension.getChildren();

			if (extensionChildren == null || extensionChildren.isEmpty()) {
				String name = extension.getName();
				String value = extension.getValue();
				System.out.println(name + " : " + value);

			} else {
				printExtensions(extensionChildren, space + " ");
			}
		}
	}

	public static void main(String args[]) {
		Session session = getSession();

		CmisObject cmisObject = session.getObject("134");

		List<CmisExtensionElement> extensions = cmisObject.getExtensions(ExtensionLevel.OBJECT);

		if (extensions == null) {
			System.out.println("Document do not have extensions");
			return;
		}
		printExtensions(extensions, " ");
	}
}

Output

objectId : 134

name : My_Document-0-1
