Purpose
There are different purposes for extending PDT. One of them is adding support for specific PHP framework to the IDE features like: Code Assist, Navigation (CTRL + click), Presentation (Outline, PHP Explorer). In this document we'll describe how to achieve these goals using PDT extension points.
Extending
Code Assist
Type inference hinting
Suppose your framework uses the following language structure for object instantiation:
$myObject = ClassRegistry::init('MyObject');
In this case PDT type inference engine is unable to detect the type of $myObject variable, so we'll have to add a specific rule that helps him.
org.eclipse.php.core.goalEvaluatorFactories extension point allows to provide additional rules to the PHP type inference engine. For our example what we'll need to contribute is:
<extension point="org.eclipse.php.core.goalEvaluatorFactories">
<factory
class="com.xyz.php.fmwrk.XYZGoalEvaluatorFactory"
priority="100">
</factory>
</extension>
Please note the priority is set to 100 in order to override the default PHP goal evaluator (its priority is 10).
