Slowly but surely.

Thanks, we'll look into it.

Ok I've read the article and can see what can be done with virtual extension methods.

There is discussion about it on this mailing list and it seems that Mr. Brian Goetz, who is the Oracle's Java Language Architect, is strongly against using Java 8 this way, for behavior and state multiple inheritance.

So I'm thinking that this is hardly a best practise or recommended solution a problem.

Reopened, see #638

I will implement an example for this. But first I need to go read your contribution guidelines.

Ok @reegnz

from java-design-patterns.

@reegnz are you still implementing this?

from java-design-patterns.

@reegnz how slowly? I will mark this issue ready for taking again.

from java-design-patterns.

No problem. I don't develop Java nowadays.

Hi @iluwatar ,

I can add a simple app for virtual-pattern but when I studied the code a little, I saw some files that need to be added. How can I create these files. Or if I just add the sample project, would it be enough?

from java-design-patterns.

What files do you mean? I expect that implementing this pattern brings quite many new files anyway. You're not talking about source code files, are you?

I made a png file for uml diagrams but not similar with other samples and .puml file and also I saw a block almost every sample as "The MIT License

• Copyright © 2014-2019 Ilkka Seppälä".
  Is this necessary to add any sample ?

from java-design-patterns.

puml file is autogenerated from code. From that you can generate the image and it will be similar as in other pattern examples.

Similarly there is a license checker plugin in the project that will add the missing licenses for you.

@iluwatar Yes, I saw the other samples, and I researched a little and I found plantUml plugin and I tried to generate them but still I can not auto generate them. Also, I researched about auto generating for uml and png part but still could not. I implement a sample for virtual field pattern and also blackboard but just left etc folders

Can you give a link to your code? I could take a look.

from java-design-patterns.

@iluwatar , I forked the project and added a module as virtual-field, and I can not push my changes its getting denied error. Some permission problems or anything else ?

from java-design-patterns.

There shouldn't be any problems if you are trying to push to your forked repository. I can imagine that it fails if you are trying to push to the master repository - that's only allowed for collaborators.
