/**
|
|
* Represents a pre or post processing filter on HTML Purifier's output
|
|
*
|
|
* Sometimes, a little ad-hoc fixing of HTML has to be done before
|
|
* it gets sent through HTML Purifier: you can use filters to acheive
|
|
* this effect. For instance, YouTube videos can be preserved using
|
|
* this manner. You could have used a decorator for this task, but
|
|
* PHP's support for them is not terribly robust, so we're going
|
|
* to just loop through the filters.
|
|
*
|
|
* Filters should be exited first in, last out. If there are three filters,
|
|
* named 1, 2 and 3, the order of execution should go 1->preFilter,
|
|
* 2->preFilter, 3->preFilter, purify, 3->postFilter, 2->postFilter,
|
|
* 1->postFilter.
|
|
*
|
|
* @note Methods are not declared abstract as it is perfectly legitimate
|
|
* for an implementation not to want anything to happen on a step
