Constructor Details

#initialize(rp, id, pid) ⇒ ProxyObject

Constructor. This should not be called manually but through a running ‘RubyProcess’.

Examples

proxy_obj = rp.new(:String, “Kasper”) #=> <RubyProcess::ProxyObject> proxy_obj = rp.static(:File, :open, “/tmp/somefile”) #=> <RubyProcess::ProxyObject>

def initialize(rp, id, pid)
  @__rp_rp, @__rp_id, @__rp_pid = rp, id, pid
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Proxies all calls to the process-object.

Examples

str = rp.new(:String, “Kasper”) #=> <RubyProcess::ProxyObject::1> length_int = str.length #=> <RubyProcess::ProxyObject::2> length_int.__rp_marshal #=> 6

  debug "Method-missing-args-before: #{args} (#{@__rp_pid})\n" if @debug
  real_args = @__rp_rp.parse_args(args)
  debug "Method-missing-args-after: #{real_args}\n" if @debug

  return @__rp_rp.send(cmd: :obj_method, id: @__rp_id, method: method, args: real_args, &block)

#__rp_marshal ⇒ Object

Returns the object as the real object transfered by using the marshal-lib.

Examples

str = rp.new(:String, “Kasper”) #=> <RubyProcess::ProxyObject> str.__rp_marshal #=> “Kasper”
