Class Details

[line 60]
The phpDocumentor_IntermediateParser Class

This class performs the work of organizing raw data from the parser in the format of descendants of the parserElement class. This is also where processing of package pages occurs, in phpDocumentor_IntermediateParser::handleClass() for class-level packages and phpDocumentor_IntermediateParser::handleDocBlock() for page-level packages.

Most of the work of this parser goes to matching up DocBlocks with the elements that they are documenting. Since DocBlocks are passed before the element they document, the last DocBlock is stored in phpDocumentor_IntermediateParser::$last and then placed into the $docblock parameter of the parserElement descendant object.

Class Variables

$all_packages = array()

[line 186]

list of all packages encountered while documenting. Used in automatic linking.

Converter::getLink() first checks if an ambiguous link is found in the current package. If not, it then checks in parent packages, and if still not found, uses this array to check in the rest of the packages before giving up




Tags:

var:  Format: array(packagename => 1, packagename => 1,...)
see:  Converter::getLink()

Type:  array


[ Top ]

$classes =  false

[line 268]

used to keep track of inheritance at the smartest level possible for a

dumb computer



Type:  Classes


[ Top ]

$converters =  false

[line 287]

an array of template names indexed by converter name

For example, if the default HTMLframesConverter is using the DOM/l0l33t template, the array will be

  1. $converters['frames''DOM/l0l33t'




Tags:

var:  Format: array(Convertername1 => templatename)

Type:  array


[ Top ]

$cur_class =  ''

[line 88]

Name of the class currently being parsed.

It is only used (and only valid) when phpDocumentor_IntermediateParser is parsing a class



Type:  string


[ Top ]

$data =

[line 237]

$data contains parsed structures for the current page being parsed

In version 1.1+, $data is only used to store the current page information. All handling of documented elements is handled by the ProceduralPages and Classes classes.



Type:  parserData

$last =

[line 65]


Type:  parserDocBlock


[ Top ]

$lasttype =  ''

[line 80]

type of the last parser Element handled

This is used in handleDocBlock to determine whether a DocBlock is a page-level DocBlock in conjunction with the parserData::$clean var. A page-level DocBlock is alwaysthe first DocBlock in a file, and must be followed by another DocBlock. The first test is handled by parserData::$clean, which is set to false on the first encounter of an element, and the second test is handled by this variable, which must be equal to "docblock"

Type:  string


[ Top ]

$packagecategories = array()

[line 173]

Used to determine the category for tutorials.

WARNING: If more than one category exists, the last category encountered will overwrite the previous and will raise a big warning




Tags:

var:  Format: packagename => categoryname

Type:  array


[ Top ]

$packageoutput =  false

[line 206]

array of packages to parser and output documentation for, if not all packages should be documented

Format:
array(package1,package2,...)
or false if not set

Use this option to limit output similar to ignoring files. If you have some temporary files that you don't want to specify by name but don't want included in output, set a package name for all the elements in your project, and set packageoutput to that name. the default package will be ignored. Parsing speed does not improve. If you want to ignore files for speed reasons, use the ignore command-line option

$package_pages = array()

[line 133]

array of parsed package pages

used by Convert() to convert all package pages into output



Type:  array


[ Top ]

$package_parents = array()

[line 164]

Keeps track of packages of classes that have parent classes in another package. Used in automatic linking.

This array is updated by addPackageParent(), which is called in Classes::processChild() to keep track of classes that descend from classes in different packages. In other words, if class foo is in package one, and class bar is in package two, an entry $package_parents['two'] = 'one' will be made.

Type:  array


[ Top ]

$parsePrivate =  false

[line 106]

set in Setup.inc.php to the value of the parseprivate commandline

option. If this option is true, elements with an @access private tag will be parsed and displayed

[ Top ]

$privatepages = array()

[line 151]

Put away a page that has been @ignored or @access private if !$parsePrivate

When a page has @access private in its DocBlock, it is placed here instead of in $pages, to allow for proper Class parsing. Since classes and pages are parsed as if they were separate, this array allows public classes on private pages to retrieve information needed about the page that holds the class and to addPageIfNecessary() to the $pages array



Type:  array


[ Top ]

$private_class =  false

[line 113]

this variable is used to prevent parsing of elements with an @ignore tag

Class Methods


constructor phpDocumentor_IntermediateParser [line 326]

phpDocumentor_IntermediateParser phpDocumentor_IntermediateParser( [string $title = 'Generated Documentation'])

sets up basic data structures



Tags:



Parameters:

string  $title  Title of generated documentation, passed to Converters

[ Top ]

method addConverter [line 1708]

void addConverter( string $output, string $name, string $template)

Add a converter name to use to the list of converters

Sets up the $converters array.




Parameters:

string  $output  output format (HTML, PDF, XML). Must be all caps
string  $name  Converter name (frames, for example, is the name of HTMLframesConverter)
string  $template  template to use, should be a relative path to the templates dir (like DOM/default)

[ Top ]

method addElementToPage [line 1474]

void addElementToPage( parserElement $element, string $path)

adds a processed descendant of parserElement to the $pages array or $privatepages array

This function expects the page to exist in either $pages or $privatepages. It calls the parserData::addElement() method to add $element to the page.




Parameters:

parserElement  $element  this will actually be a descendant of parserElement
string  $path 

[ Top ]

method addPackageParent [line 1685]

void addPackageParent( parserClass &$class)

If the parent class of $class is in a different package, adds it to the

$package_parents array




Parameters:

parserClass  &$class 

[ Top ]

method addPage [line 1368]

void addPage( parserPage $page, string $path)

Replaces the parserPage represented by $this->pages[$path] with $page

Called by addPageIfNecessary(), handleDocBlock() and ProceduralPages::setupPages(), this method first checks to see if the page has been added. If not, it assumes that the page has either been @ignored or set with @access private with --parseprivate off, and returns addPrivatePage(). Otherwise, it sets the pages[$path] to be the parserPage $page and sets the package and subpackage to that of $page




Tags:



Parameters:

parserPage  $page 
string  $path  full path to the file

[ Top ]

method addPageIfNecessary [line 1398]

void addPageIfNecessary( string $path, &$class)

add a new parserPage to the $pages array if none is found

This method is used when a page has been @ignored or marked with @access private, and a public class is in the page (a class with no @access private in its DocBlock). The method first creates a new page in the $pages array and then copies path information, and calls addPage() to set up packages




Parameters:

string  $path  full path of page
  &$class 

[ Top ]

method addPrivatePage [line 1436]

void addPrivatePage( parserPage $page, string $path)

Adds a parserPage element to the parserData element in $this->privatepages[$path]

Tags:



Parameters:

parserPage  $page 
string  $path  full path to the page

[ Top ]

method addUses [line 1505]

void addUses( parserElement $element, string $path)

[ Top ]

method Convert [line 1650]

void Convert( $title, $converter)

Interface to the Converter

This function simply passes $pages and package_pages to the walk() method, and then calls the Output() method. Note that Output() is not required to do anything, and in fact doesn't in HTMLframesConverter.

Parameters:

mixed  $a 
mixed  $b 

[ Top ]

method handleClass [line 905]

void handleClass( integer $event, parserClass $data)

handles post-parsing of classes

This function sets $data->clean to false to tell the phpDocumentor_IntermediateParser that a page-level DocBlock can't be found after this point on this page. It sets $cur_class to its name, and if an @ignore tag is found in the DocBlock, it sets $private_class to true, to prevent post-parsing of any of the class's vars or methods. Then it checks for the existence of a package page for the class's package




Parameters:

integer  $event  Event number from Parser.inc
parserClass  $data 

[ Top ]

method handleConst [line 609]

void handleConst( integer $event, parserVar $data)

handles post-parsing of class constants

This function aligns $data's $path var and packages to match the parent object




Parameters:

integer  $event  Event number from Parser.inc
parserVar  $data 

[ Top ]

method handleDefine [line 849]

void handleDefine( integer $event, parserDefine $data)

handles post-parsing of defines

This function sets $data->clean to false to tell the phpDocumentor_IntermediateParser that a page-level DocBlock can't be found after this point on this page. It then sets the package to be the same as the page and adds itself to the ProceduralPages class




Parameters:

integer  $event  Event number from Parser.inc
parserDefine  $data 

[ Top ]

method handleDocBlock [line 1046]

void handleDocBlock( integer $event, parserDocBlock $data)

handles post-parsing of DocBlocks

This function sets $last to the DocBlock represented by $data, to allow the next documentable element passed to phpDocumentor_IntermediateParser to link the DocBlock into its $docblock property. This function also checks for two special cases of DocBlocks:

  1. First DocBlock in the file contains a @package tag
  2. First DocBlock in the file is immediately followed by another DocBlock
In both cases, the function extracts this tag and uses it as the page-level package. If the @package tag is in the DocBlock of an element (function, global variable, whatever) that isn't a page-level DocBlock, a warning will be raised to notify the author that a @package tag belongs in a page-level DocBlock.

New in version 1.2.2, if the first DocBlock in a file contains a @package tag, it is a page-level DocBlock.

If the DocBlock is page-level, it is processed with _processPageLevelDocBlock

Finally, the function replaces the old parserPage in parserData::$data->parent with the new one containing information from the DocBlock by calling addPage(), and checks for package-level docs.




Parameters:

integer  $event  Event number from Parser.inc
parserDocBlock  $data 

[ Top ]

method HandleEvent [line 1226]

void HandleEvent( integer $event, mixed $data)

called via Parser::parse() and Parser's inherited method Publisher::publishEvent()

$event is one of the PHPDOC constants from Parser.inc. If it is not PHPDOCUMENTOR_EVENT_NEWSTATE, then a function name is retrieved from the $event_handlers array and called to handle the $data




Tags:

global:  array $_phpDocumentor_setting$phpDocumentor_DefaultPackageName: we use 'sourcecode' to determine whether to highlight the source of the current file if it has no file-level docblock


Parameters:

integer  $event  event number from Parser.inc
mixed  $data  if $event is PHPDOCUMENTOR_EVENT_NEWSTATE, $data is a PHP_DOC_EVENT_END_PAGE or STATE_END_CLASS, otherwise $data is either a parserDocBlock, parserPage or descendant of parserElement

[ Top ]

method handleFunction [line 763]

void handleFunction( integer $event, parserFunction $data)

handles post-parsing of functions

This function sets $data->clean to false to tell the phpDocumentor_IntermediateParser that a page-level DocBlock can't be found after this point on this page. It then sets the package to be the same as the page, aligns the docblock's @param, @global, and @staticvar tags with the information parsed from the function source code.

If source code has been parsed by a {@source} tag, the source is added to its docblock, and then the parserFunction adds itself to the ProceduralPages class




Parameters:

integer  $event  Event number from Parser.inc
parserFunction  $data 

[ Top ]

method handleGlobal [line 459]

void handleGlobal( integer $event, parserGlobal $data)

handles post-parsing of global variables

This function sets $data->clean to false to tell the phpDocumentor_IntermediateParser that a page-level DocBlock can't be found after this point on this page. It then sets the package to be the same as the page, and adds itself to the ProceduralPages class




Parameters:

integer  $event  Event number from Parser.inc
parserGlobal  $data 

[ Top ]

method handleInclude [line 403]

void handleInclude( integer $event, parserInclude $data)

handles post-parsing of include/require/include_once/require_once

This function sets $data->clean to false to tell the phpDocumentor_IntermediateParser that a page-level DocBlock can't be found after this point on this page. It then sets the package to be the same as the page, and adds itself to the ProceduralPages class




Parameters:

integer  $event  Event number from Parser.inc
parserInclude  $data 

[ Top ]

method handleMethod [line 659]

void handleMethod( integer $event, parserMethod $data)

handles post-parsing of class methods

This function first aligns $data's path and package to match the parent object, and also aligns the docblock's @param, @global, and @staticvar tags with the information parsed from the method source code. It also checks to see if the method is a constructor and sets the $isConstructor flag. If source code has been parsed by a {@source} tag, the source is added to its docblock

Finally, it adds the method to the Classes class.




Parameters:

integer  $event  Event number from Parser.inc
parserMethod  $data 

[ Top ]

method handlePackagePage [line 515]

void handlePackagePage( integer $event, parserPackagePage $data)

Parameters:

integer  $event  Event number from Parser.inc
parserVar  $data 

[ Top ]

method Output [line 1805]

void Output( [ $title = "Generated Documentation"])

call this method once parsing has completed.

This method calls the private methods fixClasses and fixProcPages, both of which adjust inheritance and package information based on complicated post-parsing rules described in ProceduralPages::setupPages() and Classes::Inherit(). Then, it sorts elements of the $pages array and calls Convert for each Converter in the $converters array
