class AbstractMapper

The configurable base class for mappers

The mapper DSL is configured by assigning it a specific settings:

class BaseMapper < AbstractMapper::Mapper
  configure do
    command :list, List     # domain-specific command
    command :rename, Rename # domain-specific command

    rule MergeLists         # domain-specific rule
  end
end

Then a configured mapper can use a corresponding DSL commands

class ConcreteMapper < BaseMapper
  list do
    rename :foo, to: :bar
  end
end
