public mixed call()Executes a cacheable callback if not found in cache else returns cached output and result
Since arguments to this function are read with func_get_args you can pass any number of arguments to this method as long as the first argument passed is the callback definition.
The callback definition can be in several forms:
- Standard PHP Callback array see [recommended]
- Function name as a string eg. 'foo' for function foo()
- Static method name as a string eg. 'MyClass::myMethod' for method myMethod() of class MyClass
Returns: Result of the callback Since: 11.1 libraries/joomla/cache/controller/callback.php at line 59get
public mixed get(mixed callback, array args, string id, boolean wrkarounds, array woptions, string group)Executes a cacheable callback if not found in cache else returns cached output and result
Parameters: callback - Callback or string shorthand for a callback args - Callback arguments id - Cache id wrkarounds - True to use wrkarounds woptions - Workaround options Returns: Result of the callback Since: 11.1 libraries/joomla/cache/controller/callback.php at line 195
_makeId
protected string _makeId(callback callback, array args) Generate a callback cache id
Parameters: callback - Callback to cache args - Arguments to the callback method to cache Returns: MD5 Hash : function cache id Since: 11.1 Вернуться к записям по теме Joomla.ya.samposebe.ru
