Defined in:
lib/db_mod/statements/configurable_method.rb

Overview

Encapsulates a method that has just been defined via the dsl exposed in DbMod::Statements so that it can be extended with additional processing such as result coercion.

The pattern here is something similar to rack’s middleware. Calling any of the extension methods below will replace the original method defined by def_prepared or def_statement with a wrapper function that may perform processing on given arguments, pass them to the original function, then perform additional processing on the result.
