Zend\Cache\Pattern¶
Overview¶
Cache patterns are configurable objects to solve known performance bottlenecks. Each should be used only in the
specific situations they are designed to address. For example you can use one of the CallbackCache
,
ObjectCache
or ClassCache
patterns to cache method and function calls; to cache output generation, the
OutputCache
pattern could assist.
All cache patterns implement the same interface, Zend\Cache\Pattern\PatternInterface
, and most extend the abstract
class Zend\Cache\Pattern\AbstractPattern
to implement basic logic.
Configuration is provided via the Zend\Cache\Pattern\PatternOptions
class, which can simply be instantiated
with an associative array of options passed to the constructor. To configure a pattern object, you can set an
instance of Zend\Cache\Pattern\PatternOptions
with setOptions
, or provide your options (either as an
associative array or PatternOptions
instance) as the second argument to the factory.
It’s also possible to use a single instance of Zend\Cache\Pattern\PatternOptions
and pass it to multiple
pattern objects.
Quick Start¶
Pattern objects can either be created from the provided Zend\Cache\PatternFactory
factory, or, by simply
instantiating one of the Zend\Cache\Pattern\*Cache
classes.

$callbackCache = Zend\Cache\PatternFactory::factory('callback', array(
'storage' => 'apc',
));

1 2 3 4 5 | // OR, the equivalent manual instantiation:
$callbackCache = new Zend\Cache\Pattern\CallbackCache();
$callbackCache->setOptions(new Zend\Cache\Pattern\PatternOptions(array(
'storage' => 'apc',
)));

Available Methods¶
The following methods are implemented by Zend\Cache\Pattern\AbstractPattern
.
