REST Interface

Client Library

Java client library to interact with the service is distributed as maven artifact

<groupId>org.gcube.application</groupId>
<artifactId>geoportal-client</artifactId>

The library offers various wrappings of the REST interface, allowing for :

• Both Custom & Generic management of Profiled Documents ;
• Both Custom & Generic automatic parsing of JSON communications over REST interface;
• Transparent authentication and service discovery, thanks to gCube Framework;

Generic Profiled Documents Managers

• ProfiledDocumentsManagerI : JAVA interface for the management of Profiled Documents.

Custom Concessioni Managers

The library provides the following customized versions of the generic clients in order to manage Concessioni Documents :

MongoConcessioni

Interface for the stateless management of Concessioni Documents. It reflects the contract of the generic REST API. Following snippet shows typical usage :

ConcessioniManagerI

Interface for the statefull creation of Concessioni Documents. Stateful logic helps client to manage the management of the last loaded/registered Concessione, offering dedicated methods for adding FileSets (e.g. RelazioneScavo) to the current Document.

Following snippet shows typical usage :

import org.gcube.application.geoportal.client.GeoportalAbstractPlugin.statefulMongoConcessioni;
....
 
//Obtain the client
ConcessioniManagerI manager=statefulMongoConcessioni().build();
...
 
//Create a new Document from scratch
Concessione c = ...
...
manager.createNew(c);
 
//Adds an UploadedImage to the current document
 
UploadedImage toRegisterImg= ...
TempFile toUpload=....
 
manager.addImmagineRappresentativa(toRegisterImg, toUpload);
 
 
//Publishes current object
manager.publish();

Utility Classes

StorageUtils

In order to transfer FileSets to the REST service, an utility class is provided, allowing for the management of infrastructure's TempFiles. Following snippet is a typical usage :

StorageUtils storage=new StorageUtils();
 
InputStream myPayload=...
String payloadName=...
 
TempFile toUpload=storage.putOntoStorage(myPayload, payloadName);
