◆ classloader()

static core_component::classloader ( $classname )

static

Class loader for Frankenstyle named classes in standard locations.

Frankenstyle namespaces are supported.

The expected location for core classes is: 1/ core_xx_yy_zz —> lib/classes/xx_yy_zz.php 2/ core::xx_yy_zz —> lib/classes/xx_yy_zz.php 3/ core::xx::yy_zz —> lib/classes/xx/yy_zz.php

The expected location for plugin classes is: 1/ mod_name_xx_yy_zz —> mod/name/classes/xx_yy_zz.php 2/ mod_name::xx_yy_zz —> mod/name/classes/xx_yy_zz.php 3/ mod_name::xx::yy_zz —> mod/name/classes/xx/yy_zz.php

Parameters

string $classname

◆ fetch_component_source()

static core_component::fetch_component_source ( string $key )

staticprotected

Returns the component source content as loaded from /lib/components.json.

Return values

array

◆ fetch_core_version()

static core_component::fetch_core_version ( )

staticprotected

Get the core version.

In order for this to work properly, opcache should be reset beforehand.

Return values

float core version.

◆ fetch_plugins()

static core_component::fetch_plugins	(	$plugintype,
		$fulldir
	)

staticprotected

Returns list of plugins of given type in given directory.

Parameters

string	$plugintype
string	$fulldir

Return values

array

◆ fetch_plugintypes()

static core_component::fetch_plugintypes ( )

staticprotected

Returns list of known plugin types.

Return values

array

◆ fetch_subsystems()

static core_component::fetch_subsystems ( )

staticprotected

Returns list of core subsystems.

Return values

array

◆ fetch_subtypes()

static core_component::fetch_subtypes ( $ownerdir )

staticprotected

Returns list of subtypes.

Parameters

string $ownerdir

Return values

array

◆ fill_filemap_cache()

static core_component::fill_filemap_cache ( )

staticprotected

Fills up the cache defining what plugins have certain files.

See also: self::get_plugin_list_with_file

Return values

void

◆ get_cache_content()

static core_component::get_cache_content ( )

static

Create cache file content.

this is intended for $CFG->alternative_component_cache only.

Return values

string

◆ get_class_file()

static core_component::get_class_file	(	$class,
		$prefix,
		$path,
		$separators
	)

staticprotected

Return the path to the class based on the given namespace prefix and path it corresponds to.

Will return the path even if the file does not exist. Check the file esists before requiring.

Parameters

string	$class	the name of the class.
string	$prefix	The namespace prefix used to identify the base directory of the source files.
string	$path	The relative path to the base directory of the source files.
string[]	$separators	The characters that should be used for separating.

Return values

string|bool The full path to the file defining the class. Or false if it could not be resolved.

◆ is_developer()

static core_component::is_developer ( )

staticprotected

Are we in developer debug mode?

Note: You need to set "$CFG->debug = (E_ALL | E_STRICT);" in config.php, the reason is we need to use this before we setup DB connection or caches for CFG.

Return values

bool

◆ load_classes()

static core_component::load_classes	(	$component,
		$fulldir,
		$namespace = `''`
	)

staticprotected

Find classes in directory and recurse to subdirs.

Parameters

string	$component
string	$fulldir
string	$namespace

◆ psr_classloader()

static core_component::psr_classloader ( $class )

staticprotected

Return the path to a class from our defined PSR-0 or PSR-4 standard namespaces on demand.

Only returns paths to files that exist.

Adapated from http://www.php-fig.org/psr/psr-4/examples/ and made PSR-0 compatible.

Parameters

string $class the name of the class.

Return values

string|bool The full path to the file defining the class. Or false if it could not be resolved or does not exist.
