Class: cachestore_mongodb - X-Ref
The MongoDB Cache store.__construct($name, array $configuration = array() X-Ref |
Constructs a new instance of the Mongo store. Noting that this function is not an initialisation. It is used to prepare the store for use. The store will be initialised when required and will be provided with a cache_definition at that time. param: string $name param: array $configuration |
are_requirements_met() X-Ref |
Returns true if the requirements of this store have been met. return: bool |
get_supported_features(array $configuration = array() X-Ref |
Returns the supported features. param: array $configuration return: int |
get_supported_modes(array $configuration = array() X-Ref |
Returns an int describing the supported modes. param: array $configuration return: int |
initialise(cache_definition $definition) X-Ref |
Initialises the store instance for use. Once this has been done the cache is all set to be used. param: cache_definition $definition |
is_initialised() X-Ref |
Returns true if this store instance has been initialised. return: bool |
is_ready() X-Ref |
Returns true if this store instance is ready to use. return: bool |
is_supported_mode($mode) X-Ref |
Returns true if the given mode is supported by this store. param: int $mode return: bool |
supports_multiple_identifiers() X-Ref |
Returns true if this store is making use of multiple identifiers. return: bool |
get($key) X-Ref |
Retrieves an item from the cache store given its key. param: string $key The key to retrieve return: mixed The data that was associated with the key, or false if the key did not exist. |
get_many($keys) X-Ref |
Retrieves several items from the cache store in a single transaction. If not all of the items are available in the cache then the data value for those that are missing will be set to false. param: array $keys The array of keys to retrieve return: array An array of items from the cache. |
set($key, $data) X-Ref |
Sets an item in the cache given its key and data value. param: string $key The key to use. param: mixed $data The data to set. return: bool True if the operation was a success false otherwise. |
set_many(array $keyvaluearray) X-Ref |
Sets many items in the cache in a single transaction. param: array $keyvaluearray An array of key value pairs. Each item in the array will be an associative array with two return: int The number of items successfully set. It is up to the developer to check this matches the number of items |
delete($key) X-Ref |
Deletes an item from the cache store. param: string $key The key to delete. return: bool Returns true if the operation was a success, false otherwise. |
delete_many(array $keys) X-Ref |
Deletes several keys from the cache in a single action. param: array $keys The keys to delete return: int The number of items successfully deleted. |
purge() X-Ref |
Purges the cache deleting all items within it. return: boolean True on success. False otherwise. |
config_get_configuration_array($data) X-Ref |
Takes the object from the add instance store and creates a configuration array that can be used to initialise an instance. param: stdClass $data return: array |
config_set_edit_form_data(moodleform $editform, array $config) X-Ref |
Allows the cache store to set its data against the edit form before it is shown to the user. param: moodleform $editform param: array $config |
instance_deleted() X-Ref |
Performs any necessary clean up when the store instance is being deleted. |
initialise_test_instance(cache_definition $definition) X-Ref |
Generates an instance of the cache store that can be used for testing. param: cache_definition $definition return: false |
unit_test_configuration() X-Ref |
Generates an instance of the cache store that can be used for testing. param: cache_definition $definition return: false |
my_name() X-Ref |
Returns the name of this instance. return: string |
ready_to_be_used_for_testing() X-Ref |
Returns true if this cache store instance is both suitable for testing, and ready for testing. Cache stores that support being used as the default store for unit and acceptance testing should override this function and return true if there requirements have been met. return: bool |
