Module: EXEL::Middleware

Defined in:

lib/exel/middleware/chain.rb,
lib/exel/middleware/logging.rb

Overview

Middleware is code configured to run around each processor execution. Custom middleware can be added as follows:

EXEL.configure do |config|
  config.middleware.add(MyMiddleware)
  config.middleware.add(AnotherMiddleware, 'constructor arg')
end

Middleware can be any class that implements a call method that includes a call to yield:

class MyMiddleware
  def call(processor, context, args)
    puts 'before process'
    yield
    puts 'after process'
  end
end

The call method will be passed the class of the processor that will be executed, the current context, and any args that were passed to the processor in the job definition.
