Relation samples

Basics

On most methods, you'll see the parameter named "nodeId". The value of this parameter can be a valid document, folder, mail or record UUID or path.

Example of nodeId:

  • Using UUID -> "f123a950-0329-4d62-8328-0ff500fd42db"

Suggested code sample

First, you must create the webservice object:

OKMWebservices ws = OKMWebservicesFactory.newInstance(host);

Then should log in using the method "login". You can access the "login" method from webservice object "ws" as is shown below:

ws.login(user, password);

Once logged with the webservices, the session is kept in the webservice Object. Then you can use the other API method.

At this point, you can use all the Relation methods from the "relation" class as shown below:

ws.relation.getRelationTypes(RelationType.BIDIRECTIONAL);

Methods

getRelationTypes

getAllRelationGroups

Description:

MethodReturn valuesDescription

getAllRelationGroups(int relationTypeId, String filter, int offset, int limit)

RelationGroupResultSet

Retrieves a list of all related groups.

The parameter "limit" and "offset" allows you to retrieve just a portion of the results of a query.

  • The parameter "limit" limits the number of results returned.
  • The parameter "offset" says to skip that many results before the beginning to return results.

For example, if your query has 1000 results, but you only want to return the first 10, you should use these values:

  • limit=10
  • offset=0

Now suppose you want to show the results from 11-20; you should use these values:

  • limit=10
  • offset=10

Example:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using com.openkm.sdk4csharp;
using com.openkm.sdk4csharp.bean;

namespace OKMRest
{
    public class Program
    {
        static void Main(string[] args)
        {
            String host = "http://localhost:8080/openkm";
            String username = "okmAdmin";
            String password = "admin";
            OKMWebservice ws = OKMWebservicesFactory.newInstance(host); 
             try {
ws.login(user, password);
int relationTypeId = 1;
String filter = ""; RelationGroupResultSet resultSet = ws.relation.getAllRelationGroups(relationTypeId, filter, 0, 10);
foreach (RelationGroup relationGroup in resultSet.results)
{
Console.WriteLine(relationGroup.toString());
} } catch (Exception e) { System.Console.WriteLine(e.ToString()); } } } }
