BaSyx.Examples.Snippets.AASConnection.Java

This code snippet illustrates the connection to an Asset Administration Shell (AAS) using the Java SDK with the ConnectedAssetAdministrationShellManager class. It illustrates the connection to an AAS with a known ID, as well as reading and updating of properties.

The BaSys setup for this code snippet is the following:

BaSyx.Snippet.AASConnectorConnection.Java.png


The BaSys setup consists of a Apache Tomcat server that runs BaSyx Servlets. It contains a sub model provider that exports an example Asset Administration Shell (see here for example). The snippet code runs in context of an application. The application contains the example code and a precompiled BaSyx directory that is used for resolving AAS and sub model IDs to network addresses. The following application code accesses the AAS:

// Create manager using the directory stub an the HTTPConnectorProvider
ConnectedAssetAdministrationShellManager manager = new ConnectedAssetAdministrationShellManager(connManager);
 
// Retrieve dummy AAS (created by factory) with SDK connector
IAssetAdministrationShell shell = manager.retrieveAAS("aas-001");
// - Retrieve AAS values and compare to expected values
assertTrue(shell.getId().equals("aas-001"));


The code first creates a connected Asset Administration Shell manager that creates connections to Asset Administration Shells. It uses a ConnectionManager class to create the connection and to resolve AAS and sub model IDs:

// Create manager using the directory stub an the HTTPConnectorProvider
ConnectedAssetAdministrationShellManager manager = new ConnectedAssetAdministrationShellManager(connManager);


The following code connects to the AAS with ID "aas-001". It returns a IAssetAdministrationShell instance that provides a local proxy for the remote AAS.

// Retrieve dummy AAS (created by factory) with SDK connector
IAssetAdministrationShell shell = manager.retrieveAAS("aas-001");


The following code accesses the meta property idShort of the AAS and compares its value to the expected value "aas-001"

// - Retrieve AAS values and compare to expected values
assertTrue(shell.getId().equals("aas-001"));


The complete, executable code is available in the basyx.examples project in package <<<>>>.
