|
<p>The classes in this library follow a few naming conventions, which may
|
|
help you find the correct functionality more quickly. Here they are:</p>
|
|
|
|
<dl>
|
|
|
|
<dt>All classes occupy the HTMLPurifier pseudo-namespace.</dt>
|
|
<dd>This means that all classes are prefixed with HTMLPurifier_. As such, all
|
|
names under HTMLPurifier_ are reserved. I recommend that you use the name
|
|
HTMLPurifierX_YourName_ClassName, especially if you want to take advantage
|
|
of HTMLPurifier_ConfigDef.</dd>
|
|
|
|
<dt>All classes correspond to their path if library/ was in the include path</dt>
|
|
<dd>HTMLPurifier_AttrDef is located at HTMLPurifier/AttrDef.php; replace
|
|
underscores with slashes and append .php and you'll have the location of
|
|
the class.</dd>
|
|
|
|
<dt>Harness and Test are reserved class names for unit tests</dt>
|
|
<dd>The suffix <code>Test</code> indicates that the class is a subclass of UnitTestCase
|
|
(of the Simpletest library) and is testable. "Harness" indicates a subclass
|
|
of UnitTestCase that is not meant to be run but to be extended into
|
|
concrete test cases and contains custom test methods (i.e. assert*())</dd>
|
|
|
|
<dt>Class names do not necessarily represent inheritance hierarchies</dt>
|
|
<dd>While we try to reflect inheritance in naming to some extent, it is not
|
|
guaranteed (for instance, none of the classes inherit from HTMLPurifier,
|
|
the base class). However, all class files have the require_once
|
|
declarations to whichever classes they are tightly coupled to.</dd>
|
|
|
|
<dt>Strategy has a meaning different from the Gang of Four pattern</dt>
|
|
<dd>In Design Patterns, the Gang of Four describes a Strategy object as
|
|
encapsulating an algorithm so that they can be switched at run-time. While
|
|
our strategies are indeed algorithms, they are not meant to be substituted:
|
|
all must be present in order for proper functioning.</dd>
|
|
|
|
<dt>Abbreviations are avoided</dt>
|
|
<dd>We try to avoid abbreviations as much as possible, but in some cases,
|
|
abbreviated version is more readable than the full version. Here, we
|
|
list common abbreviations:
|
|
<ul>
|
|
<li>Attr(s) to Attribute(s)</li>
|
|
<li>Def to Definition</li>
|
|
</ul>
|
|
</dd>
|
|
|
|
<dt>Ambiguity concerning the definition of Def/Definition</dt>
|
|
<dd>While a definition normally defines the structure/acceptable values of
|
|
an entity, most of the definitions in this application also attempt
|
|
to validate and fix the value. I am unsure of a better name, as
|
|
"Validator" would exclude fixing the value, "Fixer" doesn't invoke
|
|
the proper image of "fixing" something, and "ValidatorFixer" is too long!
|
|
Some other suggestions were "Handler", "Reference", "Check", "Fix",
|
|
"Repair" and "Heal".</dd>
|
|
|
|
<dt>Transform not Transformer</dt>
|
|
<dd>Transform is both a noun and a verb, and thus we define a "Transform" as
|
|
something that "transforms," leaving "Transformer" (which sounds like an
|
|
electrical device/robot toy).</dd>
