Member Function Documentation

◆ delete()

WinCacheBagOStuff::delete ( $key )

Delete an item.

Parameters

string $key

Returns: bool True if the item was deleted or not found, false on failure

Reimplemented from BagOStuff.

Definition at line 48 of file WinCacheBagOStuff.php.

◆ doGet()

WinCacheBagOStuff::doGet	(	$key,
		$flags = `0`
	)

protected

Parameters

string	$key
integer	$flags	Bitfield of BagOStuff::READ_* constants [optional]

Returns: mixed Returns false on failure and if the item does not exist

Reimplemented from BagOStuff.

Definition at line 31 of file WinCacheBagOStuff.php.

References unserialize().

◆ merge()

WinCacheBagOStuff::merge	(		$key,
		callable	$callback,
			$exptime = `0`,
			$attempts = `10`,
			$flags = `0`
	)

Merge changes into the existing cache value (possibly creating a new one)

The callback function returns the new value given the current value (which will be false if not present), and takes the arguments: (this BagOStuff, cache key, current value, TTL). The TTL parameter is reference set to $exptime. It can be overriden in the callback.

Parameters

string	$key
callable	$callback	Callback method to be executed
int	$exptime	Either an interval in seconds or a unix timestamp for expiry
int	$attempts	The amount of times to attempt a merge in case of failure
int	$flags	Bitfield of BagOStuff::WRITE_* constants

Returns: bool Success

Exceptions

InvalidArgumentException

Reimplemented from BagOStuff.

◆ set()

WinCacheBagOStuff::set	(	$key,
		$value,
		$exptime = `0`,
		$flags = `0`
	)

Set an item.

Parameters

string	$key
mixed	$value
int	$exptime	Either an interval in seconds or a unix timestamp for expiry
int	$flags	Bitfield of BagOStuff::WRITE_* constants

Returns: bool Success
