What's this?

__define_runner(symbol) public

Make the run_callbacks :save method. The generated method takes a block that it’ll yield to. It’ll call the before and around filters in order, yield the block, and then run the after filters.

run_callbacks :save do

  save

end

The run_callbacks :save method can optionally take a key, which will be used to compile an optimized callback method for each key. See #define_callbacks for more information.
