The XCache adapter is meant to be used through the Cache interface,
which abstracts away key generation, adapter instantiation and filter
implementation.
A simple configuration of this adapter can be accomplished in app/config/bootstrap/cache.php
as follows:
{{{
use lithium\storage\Cache;
Cache::config(array(
'cache-config-name' => array(
'adapter' => 'XCache',
'username' => 'user',
'password' => 'pass'
)
));
}}}
Note that the username and password configuration fields are only required if
you wish to use XCache::clear() - all other methods do not require XCache administrator
credentials.
This XCache adapter provides basic support for write, read, delete
and clear cache functionality, as well as allowing the first four
methods to be filtered as per the Lithium filtering system.
This adapter does *not* allow multi-key operations for any methods.

{
$XCache = new XCache(array('expiry' => '+5 seconds'));
$key = 'default_key';
$data = 'value';
$time = strtotime('+5 seconds');

$this->assertTrue(is_callable($closure));
$params = compact('key', 'data');
$result = $closure($XCache, $params, null);

$this->assertEqual($expected, $result);
$result = xcache_get($key);
$this->assertEqual($expected, $result);
$result = xcache_unset($key);
$this->assertTrue($result);
}
public function testIncrementWithScope()
{
$adapter = new XCache(array('scope' => 'primary'));
xcache_set('primary:key1', 1, 60);
xcache_set('key1', 1, 60);
$adapter->increment('key1');
$expected = 1;
$result = xcache_get('key1');
$this->assertEqual($expected, $result);
$expected = 2;
$result = xcache_get('primary:key1');
$this->assertEqual($expected, $result);
}
