Overview

An IRBObject is an “Internal” Ruby Object, i.e., is is created while executing a callback method that returns a Ruby Object and it stays inside a javascript script. This happens when a ruby block is passed as argument to a javascript function that expects a function as parameter. The block is converted to a javascript function in ruby_rich.rb by the call to:

// Makes a callback function from a given Ruby block
this.make_callback = function(blk) {
  return function (...args) { blk.set_this(this); return blk.run("call", ...args); }
}

When this function is called, blk.run is called, which call Callback.run. In Callback.run the arguments are converted to ruby arguments. If the block returns a ruby Object, this Object is packed in a IRBObject.

def initialize(jsvalue)

  @ruby_obj = @jsvalue.asJavaObject().ruby_obj
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(symbol, *args, &blk) ⇒ Object

An IRBObject is called with ruby arguments, so it does not need to call any process_arguments method as it is proxies a Ruby object TODO: Might actually need to process_args on the argument since we use invoke BUG!!!
