Methods

decorate()

decorate(  $parent) : void

Decorate

Decorates the child with the parent driver lib's methods and properties

Parameters

$parent

__call()

__call(  $method,   $args = array()) : mixed

__call magic method

Handles access to the parent driver library's methods

Parameters

$method
$args

Returns

mixed

__get()

__get(  $var) : mixed

__get magic method

Handles reading of the parent driver library's properties

Parameters

$var

Returns

mixed

__set()

__set(  $var,   $val) : mixed

__set magic method

Handles writing to the parent driver library's properties

Parameters

$var
$val

Returns

mixed

__construct()

__construct() : void

Class constructor

Only present so that an error message is logged if APC is not available.

get()

get(  $id) : mixed

Get

Look for a value in the cache. If it exists, return the data if not, return FALSE

Parameters

$id

Returns

mixed —

value that is stored/FALSE on failure

save()

save(string  $id, mixed  $data, integer  $ttl = 60, boolean  $raw = FALSE) : boolean

Cache Save

Parameters

string $id

Cache ID
mixed $data

Data to store
integer $ttl

Length of time (in seconds) to cache the data
boolean $raw

Whether to store the raw value (unused)

Returns

boolean —

TRUE on success, FALSE on failure

delete()

delete(  $id) : boolean

Delete from Cache

Parameters

$id

Returns

boolean —

true on success/false on failure

increment()

increment(string  $id, integer  $offset = 1) : mixed

Increment a raw value

Parameters

string $id

Cache ID
integer $offset

Step/value to add

Returns

mixed —

New value on success or FALSE on failure

decrement()

decrement(string  $id, integer  $offset = 1) : mixed

Decrement a raw value

Parameters

string $id

Cache ID
integer $offset

Step/value to reduce by

Returns

mixed —

New value on success or FALSE on failure

clean()

clean() : boolean

Clean the cache

Returns

boolean —

false on failure/true on success

cache_info()

cache_info(  $type = NULL) : mixed

Cache Info

Parameters

$type

Returns

mixed —

array on success, false on failure

get_metadata()

get_metadata(  $id) : mixed

Get Cache Metadata

Parameters

$id
