#initialize(context, &run_block) ⇒ self

def initialize(context, &run_block)
  @__context = context
  # Ruby cannot marshal procs or lambdas, so we need to define a method.
  # Binding to self allows us to intercept logging calls.
  define_singleton_method(:call, run_block.bind(self))
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

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

If the original context responds, including private methods, delegate to it

Parameters:

  • method (Symbol) —

    the method called. If context responds to this method, it will be called on the context

  • args (Array) —

    the arguments the method was called with

  • block (Proc) —

    proc called with method, if applicable

Raises:

  • (NoMethodError) —

    if the context, including private methods, does not respond to the method called
