4 | * Represents a pre or post processing filter on HTML Purifier's output | ||
5 | * | ||
6 | * Sometimes, a little ad-hoc fixing of HTML has to be done before | ||
7 | * it gets sent through HTML Purifier: you can use filters to acheive | ||
8 | * this effect. For instance, YouTube videos can be preserved using | ||
9 | * this manner. You could have used a decorator for this task, but | ||
10 | * PHP's support for them is not terribly robust, so we're going | ||
11 | * to just loop through the filters. | ||
12 | * | ||
13 | * Filters should be exited first in, last out. If there are three filters, | ||
14 | * named 1, 2 and 3, the order of execution should go 1->preFilter, | ||
15 | * 2->preFilter, 3->preFilter, purify, 3->postFilter, 2->postFilter, | ||
16 | * 1->postFilter. | ||

18 | * @note Methods are not declared abstract as it is perfectly legitimate | ||
19 | * for an implementation not to want anything to happen on a step | ||
