Instance Method Details

#provided_by(klass = nil, opts = {}) ⇒ Object

For every non-inherited public instance method on the given class, generates a method of the same name that calls it via the injector.

If a ‘layout` method is present on the class, it is given special treatment and set up so that it will be called using the Rails `layout` DSL method.

#sources ⇒ Object

An array of sources to be used for all injected methods on the host class. This is typically specified using the ‘sources` option to `provided_by`, however you can override it for more complicated dynamic behaviour.
