Re: [milo-dev] DelegateRegistry.registerEncoder()/registerDecoder() in s

[Kevin Herron <kevinherron@xxxxxxxxx>]

Hi,

Have you pulled recently? This issue should have been fixed in this PR: https://github.com/eclipse/milo/pull/31

The equivalent to what you've done would be to call DelegateRegistry.getInstance(), although it shouldn't be necessary any more.

Hi Kevin,

When milo client and server run in isolation, server output error message below:
---
"no decoder registered for encodingId=446..."

"446" means Identifiers.OpenSecureChannelRequest_Encoding_DefaultBinary.

Client was able to encode OpenSecureChannelRequest message, but server was not able to
decode this message because missing the decoder.

And so I locally wrote two classes(UaEnumerationInitializer.java and UaStructureInitializer.java)
to execute "static initializer block" of all these classes below:
---
   org.eclipse.milo.opcua.stack.core.enumerated/*.java
   org.eclipse.milo.opcua.stack.core.structured/*.java

     static {
         DelegateRegistry.registerEncoder(ApplicationType::encode, ApplicationType.class);
         DelegateRegistry.registerDecoder(ApplicationType::decode, ApplicationType.class);
     }

UaEnumerationInitializer.java)
------------------------------------------------------------------------
package org.eclipse.milo.opcua.stack.core.types;

import org.eclipse.milo.opcua.stack.core.types.enumerated.ApplicationType;
import org.eclipse.milo.opcua.stack.core.types.enumerated.AttributeWriteMask;
.....

public class UaEnumerationInitializer {
        public static void execute() {
                ApplicationType.from(null);
                AttributeWriteMask.from(null);
                AxisScaleEnumeration.from(null);
                .....
------------------------------------------------------------------------

UaStructureInitializer)
------------------------------------------------------------------------
package org.eclipse.milo.opcua.stack.core.types;

import org.eclipse.milo.opcua.stack.core.types.structured.*;

public class UaStructureInitializer {
        public static void execute() {
                new ActivateSessionRequest();
                new ActivateSessionResponse();
                .....
------------------------------------------------------------------------

And I locally added these initializer methods in constructors of UaTcpStackClient.java
and UaTcpStackClient.java.

UaTcpStackClient.java)
------------------------------------------------------------------------
     public UaTcpStackClient(UaTcpStackClientConfig config) {
         this.config = config;

       + UaEnumerationInitializer.execute();
       + UaStructureInitializer.execute();
         .....
------------------------------------------------------------------------

UaTcpStackServer.java)
------------------------------------------------------------------------
     public UaTcpStackServer(UaTcpStackServerConfig config) {
         this.config = config;

       + UaEnumerationInitializer.execute();
       + UaStructureInitializer.execute();
         .....
------------------------------------------------------------------------

Please tell me other good method for that.

Regards,
