def initialize(args)
  @args = args
  @args[:php].object_ids[self.__id__] = @args[:id]
  
  #Define finalizer so we can remove the object on PHPs side, when it is collected on the Ruby-side.
  ObjectSpace.define_finalizer(self, @args[:php].method(:objects_unsetter))
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args) ⇒ Object

Uses ‘method_missing’ to proxy all other calls onto the PHP-process and the PHP-object. Then returns the parsed result.

def method_missing(method_name, *args)
  return @args[:php].send(:type => :object_call, :method => method_name, :args => @args[:php].parse_data(args), :id => @args[:id])
end

Instance Attribute Details

#args ⇒ Object (readonly)

Contains the various data about the object like ID and class. It is readable because it needs to be converted to special hashes when used as arguments.
