| __set( $name, $value ) X-Ref |
| Makes private properties settable for backward compatibility. param: string $name Property to set. param: mixed $value Property value. return: mixed Newly-set property. |
| __isset( $name ) X-Ref |
| Makes private properties checkable for backward compatibility. param: string $name Property to check if set. return: bool Whether the property is set. |
| __unset( $name ) X-Ref |
| Makes private properties un-settable for backward compatibility. param: string $name Property to unset. |
| add( $key, $data, $group = 'default', $expire = 0 ) X-Ref |
| Adds data to the cache if it doesn't already exist. param: int|string $key What to call the contents in the cache. param: mixed $data The contents to store in the cache. param: string $group Optional. Where to group the cache contents. Default 'default'. param: int $expire Optional. When to expire the cache contents. Default 0 (no expiration). return: bool True on success, false if cache key and group already exist. |
| add_global_groups( $groups ) X-Ref |
| Sets the list of global cache groups. param: array $groups List of groups that are global. |
| decr( $key, $offset = 1, $group = 'default' ) X-Ref |
| Decrements numeric cache item's value. param: int|string $key The cache key to decrement. param: int $offset Optional. The amount by which to decrement the item's value. Default 1. param: string $group Optional. The group the key is in. Default 'default'. return: int|false The item's new value on success, false on failure. |
| delete( $key, $group = 'default', $deprecated = false ) X-Ref |
| Removes the contents of the cache key in the group. If the cache key does not exist in the group, then nothing will happen. param: int|string $key What the contents in the cache are called. param: string $group Optional. Where the cache contents are grouped. Default 'default'. param: bool $deprecated Optional. Unused. Default false. return: bool False if the contents weren't deleted and true on success. |
| flush() X-Ref |
| Clears the object cache of all data. return: true Always returns true. |
| get( $key, $group = 'default', $force = false, &$found = null ) X-Ref |
| Retrieves the cache contents, if it exists. The contents will be first attempted to be retrieved by searching by the key in the cache group. If the cache is hit (success) then the contents are returned. On failure, the number of cache misses will be incremented. param: int|string $key What the contents in the cache are called. param: string $group Optional. Where the cache contents are grouped. Default 'default'. param: bool $force Optional. Unused. Whether to force a refetch rather than relying on the local param: bool $found Optional. Whether the key was found in the cache (passed by reference). return: mixed|false The cache contents on success, false on failure to retrieve contents. |
| incr( $key, $offset = 1, $group = 'default' ) X-Ref |
| Increments numeric cache item's value. param: int|string $key The cache key to increment param: int $offset Optional. The amount by which to increment the item's value. Default 1. param: string $group Optional. The group the key is in. Default 'default'. return: int|false The item's new value on success, false on failure. |
| replace( $key, $data, $group = 'default', $expire = 0 ) X-Ref |

| reset() X-Ref |
| Resets cache keys. |
| set( $key, $data, $group = 'default', $expire = 0 ) X-Ref |
| Sets the data contents into the cache. The cache contents are grouped by the $group parameter followed by the $key. This allows for duplicate ids in unique groups. Therefore, naming of the group should be used with care and should follow normal function naming guidelines outside of core WordPress usage. The $expire parameter is not used, because the cache will automatically expire for each time a page is accessed and PHP finishes. The method is more for cache plugins which use files. param: int|string $key What to call the contents in the cache. param: mixed $data The contents to store in the cache. param: string $group Optional. Where to group the cache contents. Default 'default'. param: int $expire Not Used. return: true Always returns true. |
| stats() X-Ref |
