Examples with ExtensionObject org.eclipse.milo.opcua.stack.core.types.builtin.ExtensionObject used on opensource projects

Example 1 with ExtensionObject

use of org.eclipse.milo.opcua.stack.core.types.builtin.ExtensionObject in project milo by eclipse.

the class ExampleNamespace method addCustomUnionTypeVariable.

private void addCustomUnionTypeVariable(UaFolderNode rootFolder) throws Exception {
    NodeId dataTypeId = CustomUnionType.TYPE_ID.toNodeIdOrThrow(getServer().getNamespaceTable());
    NodeId binaryEncodingId = CustomUnionType.BINARY_ENCODING_ID.toNodeIdOrThrow(getServer().getNamespaceTable());
    UaVariableNode customUnionTypeVariable = UaVariableNode.builder(getNodeContext()).setNodeId(newNodeId("HelloWorld/CustomUnionTypeVariable")).setAccessLevel(AccessLevel.READ_WRITE).setUserAccessLevel(AccessLevel.READ_WRITE).setBrowseName(newQualifiedName("CustomUnionTypeVariable")).setDisplayName(LocalizedText.english("CustomUnionTypeVariable")).setDataType(dataTypeId).setTypeDefinition(Identifiers.BaseDataVariableType).build();
    CustomUnionType value = CustomUnionType.ofBar("hello");
    ExtensionObject xo = ExtensionObject.encodeDefaultBinary(getServer().getSerializationContext(), value, binaryEncodingId);
    customUnionTypeVariable.setValue(new DataValue(new Variant(xo)));
    getNodeManager().addNode(customUnionTypeVariable);
    customUnionTypeVariable.addReference(new Reference(customUnionTypeVariable.getNodeId(), Identifiers.Organizes, rootFolder.getNodeId().expanded(), false));
}

Example 2 with ExtensionObject

use of org.eclipse.milo.opcua.stack.core.types.builtin.ExtensionObject in project milo by eclipse.

the class UnifiedAutomationReadCustomDataTypeExample method run.

@Override
public void run(OpcUaClient client, CompletableFuture<OpcUaClient> future) throws Exception {
    // Decoding a struct with custom DataType requires a DataTypeManager
    // 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();
    ExtensionObject xo = (ExtensionObject) dataValue.getValue().getValue();
    Object value = xo.decode(client.getDynamicSerializationContext());
    logger.info("value: {}", value);
    future.complete(client);
}
