lithium\template\View::_convertSteps()

protected method

This method is deprecated.

Handles API backward compatibility by converting an array-based rendering instruction passed to render() as a process, to a set of rendering steps, rewriting any associated rendering parameters as necessary.

Parameters

array $command
A deprecated rendering instruction, i.e. array('template' => '/path/to/template').
array $params
The array of associated rendering parameters, passed by reference.
array $defaults
Default step rendering options to be merged with the passed rendering instruction information.

Returns

array

Returns a converted set of rendering steps, to be executed in render().
