Eclipse Milo: How to call method which takes a customDataType as argument?
The CustomDataType the method requires:
<UADataType NodeId="ns=1;i=3010" BrowseName="1:ScanSettings">
<DisplayName>ScanSettings</DisplayName>
<References>
<Reference ReferenceType="HasEncoding">ns=1;i=5015</Reference>
<Reference ReferenceType="HasEncoding">ns=1;i=5016</Reference>
<Reference ReferenceType="HasSubtype" IsForward="false">i=22</Reference>
</References>
<Definition Name="1:ScanSettings">
<Field DataType="Duration" Name="Duration"/>
<Field DataType="Int32" Name="Cycles"/>
<Field DataType="Boolean" Name="DataAvailable"/>
<Field IsOptional="true" DataType="LocationTypeEnumeration" Name="LocationType"/>
</Definition>
</UADataType>
MethodCall:
CallMethodRequest tCallMethodRequest = new CallMethodRequest(tObjectId, tMethodId, new Variant{});
CallMethodResult tCallMethodResult = pOpcUaClient.call(tCallMethodRequest).get();
System.out.println(tCallMethodResult.getStatusCode());
How to call a method which requires ScanSettings?
Do I need to pass the Variant-array with three Variants containing Duration, Cycles and DataAvailable?
Or
do i need to do something like this ?
EDIT:
Tried it with a ScanSettings-class and got the error:
10:08:52.655 [ua-shared-pool-2] WARN org.eclipse.milo.opcua.stack.core.serialization.OpcUaBinaryStreamEncoder - Not a built-in type: class ScanSettings

I think because there is no code generation support right now the best thing to do is take advantage of the fact the client already knows how to read data type dictionaries and turn them into generic Struct objects, as well as receive those Struct objects and encode them when necessary.
Your method call would look something like this:
Struct scanSettings = Struct.builder("ScanSettings")
.addMember("LocationTypeSpecified", 0)
.addMember("Reserved1", 0)
.addMember("Duration", 3.14)
.addMember("Cycles", 1)
.addMember("DataAvailable", false)
.build();
ExtensionObject xo = ExtensionObject.encodeAsByteString(
scanSettings,
new NodeId(1, 3010),
client.getDataTypeManager()
);
CallMethodRequest request = new CallMethodRequest(
objectId,
methodId,
new Variant{new Variant(xo)}
);
