Class Details

[line 62]
A class to handle most of the parsing operations of a doc comment element.

Extending classes should implement the getSubElements method to return a list of elements that the doc comment element contains, in the order that they appear in the element. For example a function parameter element has a type, a variable name and a comment. It should therefore implement the method as follows:

    protected function getSubElements()

    {
        return array(
                'type',
                'variable',
                'comment',
               );
    }

The processSubElement will be called for each of the sub elements to allow the extending class to process them. So for the parameter element we would have:

    protected function processSubElement($name, $content, $whitespaceBefore)

    {
        if ($name === 'type') {
            echo 'The name of the variable was '.$content;
        }
        // Process other tags.
    }
