Is it possible to copy the type of the parameter from the hint?

[PavelTurk]

Please, consider the following situation:

I need to add an observer that is a Consumer<very very long generic> and after that I need to remove it. So, I need to keep it in separate variable, so, I need to declare the type of this variable:

Consumer<very very long generic> consumer = (t) -> {};
codeArea.richChanges().addObserver(consumer);
...
codeArea.richChanges().removeObserver(consumer);

Could anyone say if it is possible to copy the type of the parameter from the hint?
