setValue() protected method Stores a value identified by a key in cache. This is the implementation of the method declared in the parent class. protected boolean setValue ( $key, $value, $duration )$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. return b

getValue() protected method Retrieves a value from cache with a specified key. This is the implementation of the method declared in the parent class. protected mixed|false getValue ( $key )$key string A unique key identifying the cached value return mixed|false The value stored in cache, false if the value is not in the cache or expired.

flushValues() protected method Deletes all values from cache. This is the implementation of the method declared in the parent class. protected boolean flushValues ( )return boolean Whether the flush operation was successful.

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

addValue() protected method Stores a value identified by a key into cache if the cache does not contain this key. This is the implementation of the method declared in the parent class. protected boolean addValue ( $key, $value, $duration )$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 wil

flushValues() protected method Deletes all values from cache. This is the implementation of the method declared in the parent class. protected boolean flushValues ( )return boolean Whether the flush operation was successful.

exists() public method Checks whether a specified key exists in the cache. 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 boolean exists ( $key )$key mixed A key identifying the cached value. This can be a simple string or a complex data structure consisting of factors
