Instance Method Details

#render(context) ⇒ Object

Render the block using the provided context object.

The context object needs to respond to #[] and #[]= (e.g. a Hash is a valid context object) and the key :processors needs to contain a Hash which maps processor names to processor objects that respond to #call.

Uses the content processors specified in the pipeline key of the options attribute to do the actual rendering.

Returns the given context with the rendered content.
