PHP 클래스 yii\caching\WinCache

To use this application component, the WinCache PHP extension must be loaded. Also note that "wincache.ucenabled" should be set to "On" in your php.ini file. See Cache manual for common cache operations that are supported by WinCache. For more details and usage information on Cache, see the guide article on caching.

메소드 상세

addValue() 보호된 메소드

This is the implementation of the method declared in the parent class.
protected addValue ( string $key, mixed $value, integer $duration ) : boolean
$key string the key identifying the value to be cached
$value mixed the value to be cached. Most often it's a string. If you have disabled [[serializer]], it could be something else.
$duration integer the number of seconds in which the cached value will expire. 0 means never expire.
리턴 boolean true if the value is successfully stored into cache, false otherwise

addValues() 보호된 메소드

The default implementation calls WinCache::addValue multiple times add values one by one. If the underlying cache storage supports multiadd, this method should be overridden to exploit that feature.
protected addValues ( array $data, integer $duration ) : array
$data array array where key corresponds to cache key while value is the value stored
$duration integer the number of seconds in which the cached values will expire. 0 means never expire.
리턴 array array of failed keys

deleteValue() 보호된 메소드

Deletes a value with the specified key from cache This is the implementation of the method declared in the parent class.
protected deleteValue ( string $key ) : boolean
$key string the key of the value to be deleted
리턴 boolean if no error happens during deletion

exists() 공개 메소드

This can be faster than getting the value from the cache if the data is big. Note that this method does not check whether the dependency associated with the cached data, if there is any, has changed. So a call to [[get]] may return false while exists returns true.
public exists ( mixed $key ) : boolean
$key mixed a key identifying the cached value. This can be a simple string or a complex data structure consisting of factors representing the key.
리턴 boolean true if a value exists in cache, false if the value is not in the cache or expired.

flushValues() 보호된 메소드

This is the implementation of the method declared in the parent class.
protected flushValues ( ) : boolean
리턴 boolean whether the flush operation was successful.

getValue() 보호된 메소드

This is the implementation of the method declared in the parent class.
protected getValue ( string $key ) : string | boolean
$key string a unique key identifying the cached value
리턴 string | boolean the value stored in cache, false if the value is not in the cache or expired.

getValues() 보호된 메소드

Retrieves multiple values from cache with the specified keys.
protected getValues ( array $keys ) : array
$keys array a list of keys identifying the cached values
리턴 array a list of cached values indexed by the keys

setValue() 보호된 메소드

This is the implementation of the method declared in the parent class.
protected setValue ( string $key, mixed $value, integer $duration ) : boolean
$key string the key identifying the value to be cached
$value mixed the value to be cached. Most often it's a string. If you have disabled [[serializer]], it could be something else.
$duration integer the number of seconds in which the cached value will expire. 0 means never expire.
리턴 boolean true if the value is successfully stored into cache, false otherwise

setValues() 보호된 메소드

Stores multiple key-value pairs in cache.
protected setValues ( array $data, integer $duration ) : array
$data array array where key corresponds to cache key while value is the value stored
$duration integer the number of seconds in which the cached values will expire. 0 means never expire.
리턴 array array of failed keys
