Can one write his own tokenizer of filter class and use it inside  
elasticsearch? Is there any API to use a user defined objects using java  
classes? (like Lucene analyzer...)

In your plugin, you can add your custom tokenizer to the AnalysisModule.

The AnalysisModule has an addProcessor method which takes  
an AnalysisBinderProcessor. Add your tokenizer to a new instance via  
the processTokenizers method. Hopefully this all makes sense!

Cheers,

Ivan
