Instance Method Details

#route(opts = {}) ⇒ Object

Note:

Requires the route class to implement parse instance method.

Execute the parser class with options as described by router configuration filtering by page_type and calling class's instance parse method.

Parameters:

  • opts (Hash) (defaults to: {}) —

    ({}) Parser initializer options (see DhEasy::Core::Plugin::Parser).

Raises:

  • (ArgumentError) —

    opts[:context] is nil.

  • (ArgumentError) —

    page_type doesn't exists within routes.

  • (NameError) —

    A class with name equal to route's class attribute doesn't exists.
