Examples with DataTypeDictionarySessionInitializer org.eclipse.milo.opcua.sdk.client.dtd.DataTypeDictionarySessionInitializer used on opensource projects

Example 1 with DataTypeDictionarySessionInitializer

use of org.eclipse.milo.opcua.sdk.client.dtd.DataTypeDictionarySessionInitializer in project milo by eclipse.

the class UnifiedAutomationReadCustomDataTypeExample method run.

    // that has the codec registered with it.
    // Add a SessionInitializer that will read any DataTypeDictionary
    // nodes present in the server every time the session is activated
    // and dynamically generate codecs for custom structures.
    client.addSessionInitializer(new DataTypeDictionarySessionInitializer(new GenericBsdParser()));
    client.connect().get();
    DataValue dataValue = client.readValue(0.0, TimestampsToReturn.Neither, NodeId.parse("ns=2;s=Demo.Static.Scalar.WorkOrder")).get();
