Class Details

[line 59]
Parses doc comments.

This abstract parser handles the following tags:

The short description and the long description
@see
@link
@deprecated
@since

Extending classes should implement the getAllowedTags() method to return the tags that they wish to process, ommiting the tags that this base class processes. When one of these tags in encountered, the process<tag_name> method is called on that class. For example, if a parser's getAllowedTags() method returns \@param as one of its tags, the processParam method will be called so that the parser can process such a tag.

The method is passed the tokens that comprise this tag. The tokens array includes the whitespace that exists between the tokens, as seperate tokens. It's up to the method to create a element that implements the DocElement interface, which should be returned. The AbstractDocElement class is a helper class that can be used to handle most of the parsing of the tokens into their individual sub elements. It requires that you construct it with the element previous to the element currently being processed, which can be acquired with the protected $previousElement class member of this class.
