Jdom: improving performances 12 Jun 2013 07:20 #7446

my thoughts about how improve performances on jcook-generated components:

- remove the dom FLY, use the simple plain item value, example:
replace all the (EXAMPLE CODE):
<?php echo JDom::_('html.fly', array(
	'dataKey' => 'title',
	'dataObject' => $row
));?>

with (EXAMPLE CODE):
<?php echo $row->title; ?>

why?
  1. mainly for better performances on long list and less server resources usage, because the jdom is not involved on this code
  2. better code view

replace all the enumlist output (EXAMPLE CODE):
<?php echo JDom::_('html.fly.enum', array(
	'dataKey' => 'type',
	'dataObject' => $row,
	'labelKey' => 'text',
	'list' => ComponentHelper::enumList('fields', 'type'),
	'listKey' => 'value'
));?>

with (EXAMPLE CODE):
<?php echo $this->lists['enum']['fields.type'][$row->type]['text']; ?>

why?
  1. the function "ComponentHelper::enumList" is called just ONCE in the view.html.php and then used for all the rows, instead of call the function N rows times. I know the function doesn't requires a lot of resources (if not modified) but it's still prefereable to avoid to call it N times for the same values.

You are right.

The simple html.fly seems to do nothing. Right.

But when you add some parameters :
responsive, aclAccess, etc... then you can can the visibility depending of the rights or the screen size.
It is only an example.

When you want to optimize your component, you can replace critical JDom call to their optimized code.
For example in huges lists it is better to optimize, removing JDom for the grid rows.
Coding is now a piece of cake

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
