Inspect a process model's data

This article shows how to use the ADOXX API to retrieve details for a specific model.

The snippet below will fetch the details for a model whose ID we retrieved (e.g. via a search call) and for which we now want to retrieve details about the contained objects and relations. We also want to fetch the name and description of the model.

note

The snippet below uses Basic Authentication.

Replace the values in angle brackets with values that fit your setup, e.g. instead of <HOST> use the host at which you access your ADOxx instance.

Source Code

public class GetModelData
{
public static void main (final String [] args) throws ClientProtocolException, IOException
{
final CloseableHttpClient aClient = HttpClients.createDefault ();

final String sUser = "<USER>";
final String sPass = "<PASSWORD>";
final String sRepoID = "<REPO_ID>";
final String sModelID = "<MODEL_ID>";
String sPath = "http://<HOST>:<PORT>/ADONIS/rest/2.0/repos/" +
sRepoID +
"/models/" +
sModelID +
"?";

final List <Entry <String, String>> aSearchParameters = new ArrayList <Map.Entry <String, String>> ();
aSearchParameters.add (new AbstractMap.SimpleEntry <> ("attribute", "NAME"));
aSearchParameters.add (new AbstractMap.SimpleEntry <> ("attribute", "A_DESCRIPTION"));

// Iterate through the search parameters and construct the URL
for (final Entry <String, String> aParam : aSearchParameters)
{
final String sParamName = aParam.getKey ();
final String sParamValue = aParam.getValue ();
sPath += sParamName + "=" + URLEncoder.encode (sParamValue, "UTF-8") + "&";
}
final HttpGet aMethod = new HttpGet (sPath);

// The headers controlling the return type and the language do not have to be considered for
// token generation
aMethod.addHeader ("Accept", "application/json");
aMethod.addHeader ("Accept-Language", "en");

// Construction of the header to pass the basic authentication information
aMethod.addHeader ("Authorization",
"Basic " +
DatatypeConverter.printBase64Binary ((sUser + ":" + sPass).getBytes ()));

final CloseableHttpResponse aResponse = aClient.execute (aMethod);

try
{
final String sResult = EntityUtils.toString (aResponse.getEntity (), "UTF-8");
final StatusLine aStatusLine = aResponse.getStatusLine ();
System.out.println ("Status Code: " + aStatusLine.getStatusCode ());
System.out.println ("Result: \n" + sResult);
}
catch (final Exception aEx)
{
aEx.printStackTrace ();
}
finally
{
aResponse.close ();
}
}
}

The result should look similar to the following:

Status Code: 200
Result:
{
"locale": "en",
"item": {
"rest_links": [ ... ],
"id": " ... ",
"name": " ... ",
"type": " ... ",
"artefactType": " ... ",
"metaName": " ... ",
"link": { ... },
"icon": { ... },
"attributes": [ ... ],
