Java interoperation; lambda to callbacks?


#1

Hey I have a quick question. Will jruby convert my lambdas to java
callbacks? To be more specific, I’m working with JavaFX (with JRubyFX)
and
I have a method setCellValueFactory() that expects takes a java Callback
as
a parameter. Since Java 8 added lambdas, the java code might be
something
like this:

#2

col.setCellValueFactory( cellData -> cellData.getValue())

Would this code be equivalent to writing the jruby code:

col.set_cell_value_factory( lambda { |data| data.get_value } )

Will jruby do the correct conversion? Perhaps I should use Proc instead
of
lambda?

Thanks in advance for the help

P.S. Sorry about splitting this up into 2 emails

Well the method works with a lambda so I assume either jruby or jrubyfx
is
handling that conversion.
