gRPC-Web for GWT and/or J2CL?
Hi, It seems like gRPC has gone GA. https://www.cncf.io/blog/2018/10/24/grpc-web-is-going-ga/ It seems it can emit closure annotated classes and I guess it would be not too hard to output the equivalent jsinterop annotated classes. This would make it very easy to get excellent integration into J2CL and event GWT2.x. Eyeballing it makes it seem like a very attractive target. Has anyone used it or done any work with it before? Or know of any equivalent GWTish generator for it. -- Cheers, Peter Donald -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Orientation For GWT Mobile Application
Is there any chance to identify the Orientation of the application and change the orientation for the application in GWT.

Specifically, vdsmTaskIds is not an empty list, it's 'null'; as in "vdsmTaskIds == null" would be 'true', and "vdsmTaskIds.isEmpty()" would throw a NullPointerException. > > вторник, 23 октября 2018 г., 14:50:33 UTC+3 пользователь Thomas Broyer > написал: >> >> >> >> On Tuesday, October 23, 2018 at 1:16:57 PM UTC+2, Anastasiya Ruzhanskaya >> wrote: >>> >>> Dear Thomas, >>> thank you a lot for a detailed answer! >>> >>> I saw this documentation, but seems should look more thoroughly into >>> serialization inside GWT. >>> >>> Concerning the numbers 0|5|0|0|0 - after VmOperationParameterBase class >>> where there is a private field vmId we move down to ActionParameterBase >>> class (as you said), so 0 here will correspond to the first parameter >>> inside this class in alphabetical order (seems commanId)?

Re: parsing GWT messages in oVirt project (webadmin interface)
A null is a null, it has no "runtime type". Whenever you're unserializing a Java object (non primitive, non String) value, you'll have: - either a 0, which means 'null' (and then you're done, there's nothing else to learn about a 'null') - or a positive number, which references the runtime type in the string table. This guides you to how you'll deserialize that value (look for a CustomFieldSerializer, otherwise use the zero-arg constructor then deserialize the object's fields). For example, the declared type (of the method parameter, or of an object's field) could be java.lang.Number, the runtime type will be any of its subclasses: java.lang.Double, java.lang.Long, java.math.BigDecimal, etc. those types will be (de)serialized in different ways. - or a negative number, referencing an object that has previously been deserialized (so you already know its actual type, etc.) On Wednesday, October 24, 2018 at 6:53:21 AM UTC+2, Anastasiya Ruzhanskaya wrote: > > Yes, -6 was the reference to already serialized values, seems from the > previous calls. > > Also I would like to ask, if there is a zero value in place where I see > there should a type description in a payload, this means that we don't know > how to decode it in runtime, but there will be some following info, or it > is just 0 and we move to the next field in the class?
