Module: Ethon::Easy::ResponseCallbacks
- Included in:
- Ethon::Easy
- Defined in:
- lib/ethon/easy/response_callbacks.rb
Overview
This module contains the logic for the response callbacks. The on_complete callback is the only one at the moment.
You can set multiple callbacks, which are then executed in the same order.
easy.on_complete { p 1 }
easy.on_complete { p 2 }
easy.complete
#=> 1
#=> 2
You can clear the callbacks:
easy.on_complete { p 1 }
easy.on_complete { p 2 }
easy.on_complete.clear
easy.on_complete
#=> []
