Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

# File 'lib/packet.rb', line 195

def method_missing(name, *args)
	name = name.to_s
	if name[-1..-1] == "=" then
		# Setter
		var = name[0..-2].to_sym
		throw "The method #{name} does not exist in #{self.class.name}" if @structure.assoc(var).nil?
		index = @structure.index{|v| v[0] == var}
		@data[index] = [var, args[0]]
	else
		# Getter
		var = name.to_sym
		throw "The method #{name} does not exist in #{self.class.name}" if @structure.assoc(var).nil?
		@data.assoc(var)[1]
	end
end

		@data << [var[0], value]
	end
	data
end

#encode ⇒ Object
