	)		`[static, protected]`

Sets the various cache information to the parameters.

static eZURLWildcard::cleanup ( $ baseURL ) [static]

Removes a wildcard based on a source_url.

The URL should be provided without the /* prefix: foobar will remove the wildcard with source_url = foobar/*

Parameters:

string $baseURL URL prefix matched against destination_url

Returns:: void

Definition at line 115 of file ezurlwildcard.php.

static eZURLWildcard::createWildcardsIndex ( ) [static, protected]

Create the wildcard cache.

The wildcard caches are splitted between several files: 'wildcard_<md5>_index.php': contains regexps for wildcards 'wildcard_<md5>_0.php', 'wildcard_<md5>_1.php', ... 'wildcard_<md5>_N.php': contains cached wildcards. Each file has info about eZURLWildcard::WILDCARDS_PER_CACHE_FILE wildcards.

Returns:: void

static eZURLWildcard::definition ( ) [static]

Returns the definition for the object, the default implementation is to return an empty array.

It's upto each inheriting class to return a proper definition array.

The definition array is an associative array consists of these keys:

fields: an associative array of fields which defines which database field (the key) is to fetched and how they map to object member variables (the value).
keys: an array of fields which is used for uniquely identifying the object in the table.
function_attributes: an associative array of attributes which maps to member functions, used for fetching data with functions.

set_functions: an associative array of attributes which maps to member functions, used for setting data with functions.
increment_key: the field which is incremented on table inserts.
class_name: the classname which is used for instantiating new objecs when fetching from the database.
sort: an associative array which defines the default sorting of lists, the key is the table field while the value is the sorting method which is either 'asc' or 'desc'.
name: the name of the database table

Example: public static function definition() { return array( "fields" => array( "id" => "ID", "version" => "Version", "name" => "Name" ), "keys" => array( "id", "version" ), "function_attributes" => array( "current" => "currentVersion", "class_name" => "className" ), "increment_key" => "id", "class_name" => "eZContentClass", "sort" => array( "id" => "asc" ), "name" => "ezcontentclass" ); }

Returns:: array
