Magento 2 Observer Event for core_block_abstract_to_html_after Replacement

event-observermagento2

I use the "core_block_abstract_to_html_after" event in magento 1. What is the equivalent in Magento 2?

It seems that \Magento\Framework\View\Element\AbstractBlock::toHtml haven't such event. You can achieve such result in different ways:

If you need to add some customization for specific block, you can use it's _afterToHtml method.
To customize all block's output globally, use plugin for Magento\Framework\View\Element\AbstractBlock and implement aftreToHtml method. More information available here: http://devdocs.magento.com/guides/v2.0/extension-dev-guide/plugins.html

Who Called the Event/Observer in Magento 1.8?

Events like *_load_after have no information where or by whom they were called.

But using request object you can get area, mudule, controller and action name and check them as you want.

    $oArea           = Mage::app()->getArea();
    $oRequest        = Mage::app()->getRequest();
    $sModuleName     = $oRequest->getModuleName();
    $sControllerName = $oRequest->getControllerName();
    $sAtionName      = $oRequest->getActionName();

But you will have problem if some model (in your case sales_order) can be called twice on the same page.
