# frozen_string_literal: true
module ActionView
# This class defines the interface for a renderer. Each class that
# subclasses +AbstractRenderer+ is used by the base +Renderer+ class to
# render a specific type of object.
#
# The base +Renderer+ class uses its +render+ method to delegate to the
# renderers. These currently consist of
#
# PartialRenderer - Used for rendering partials
# TemplateRenderer - Used for rendering other types of templates
# StreamingTemplateRenderer - Used for streaming
#
# Whenever the +render+ method is called on the base +Renderer+ class, a new
# renderer object of the correct type is created, and the +render+ method on
# that new object is called in turn. This abstracts the setup and rendering
# into a separate classes for partials and templates.
