Methods
clear()
Deletes all items in the pool.
public
clear() : bool
Return values
bool —True if the pool was successfully cleared. False if there was an error.
commit()
Persists any deferred cache items.
public
commit() : bool
Return values
bool —True if all not-yet-saved items were successfully saved or there were none. False otherwise.
deleteItem()
Removes the item from the pool.
public
deleteItem(mixed $key) : bool
Parameters
- $key : mixed
-
The key to delete.
Return values
bool —True if the item was successfully removed. False if there was an error.
deleteItems()
Removes multiple items from the pool.
public
deleteItems(array<string|int, mixed> $keys) : bool
Parameters
- $keys : array<string|int, mixed>
-
An array of keys that should be removed from the pool.
Return values
bool —True if the items were successfully removed. False if there was an error.
getItem()
Returns a Cache Item representing the specified key.
public
getItem(mixed $key) : CacheItemInterface
Parameters
- $key : mixed
-
The key for which to return the corresponding Cache Item.
Return values
CacheItemInterface —The corresponding Cache Item.
getItems()
Returns a traversable set of cache items.
public
getItems([array<string|int, mixed> $keys = [] ]) : array<string|int, mixed>|Traversable
Parameters
- $keys : array<string|int, mixed> = []
-
An indexed array of keys of items to retrieve.
Return values
array<string|int, mixed>|Traversable —A traversable collection of Cache Items keyed by the cache keys of each item. A Cache item will be returned for each key, even if that key is not found. However, if no keys are specified then an empty traversable MUST be returned instead.
hasItem()
Confirms if the cache contains specified cache item.
public
hasItem(mixed $key) : bool
Parameters
- $key : mixed
-
The key for which to check existence.
Return values
bool —True if item exists in the cache, false otherwise.
save()
Persists a cache item immediately.
public
save(CacheItemInterface $item) : bool
Parameters
- $item : CacheItemInterface
-
The cache item to save.
Return values
bool —True if the item was successfully persisted. False if there was an error.
saveDeferred()
Sets a cache item to be persisted later.
public
saveDeferred(CacheItemInterface $item) : bool
Parameters
- $item : CacheItemInterface
-
The cache item to save.
Return values
bool —False if the item could not be queued or if a commit was attempted and failed. True otherwise.
isValidKey()
Determines if the provided key is valid.
private
isValidKey(string $key) : bool
Parameters
- $key : string
