Defined in:

Overview

Finds class according to the resource’s context:

module Foo

class TestResource
end

module Bar
  class TestResource
  end
end

end

Using Dayman to fetch a Foo::Bar::TestResource containing a { type: ‘test_resources’ } object ClassFinder will look for the first TestResource class starting from Foo::Bar::TestResource’s nesting. If Foo::Bar::TestResource did not exist, it would find Foo::TestResource instead.
