공개 프로퍼티들

프로퍼티	타입	설명
$_automaticCleaningFactor	integer	The automatic cleaning process destroy too old (for the given life time) cache files when a new cache file is written. 0 => no automatic cache cleaning 1 => systematic cache cleaning x (integer) > 1 => automatic cleaning randomly 1 times on x cache write
$_automaticSerialization	boolean	it can be used to save directly datas which aren't strings (but it's slower)
$_cacheDir	string	Directory where to put the cache files (make sure to add a trailing slash)
$_caching	boolean	(can be very usefull for the debug of cached scripts)
$_errorHandlingAPIBreak	boolean	In CACHE_LITE_ERROR_RETURN mode, error handling was not good because for example save() method always returned a boolean (a PEAR_Error object would be better in CACHE_LITE_ERROR_RETURN mode). To correct this without breaking the API, this option (false by default) can change this handling.
$_file	string	File name (with path)
$_fileLocking	boolean	(can avoid cache corruption under bad circumstances)
$_fileName	string	File name (without path)
$_fileNameProtection	boolean	if set to true, you can use any cache id or group name if set to false, it can be faster but cache ids and group names will be used directly in cache file names so be carefull with special characters...
$_group	string	Current cache group
$_hashedDirectoryLevel	integer	Set the hashed directory structure level. 0 means "no hashed directory structure", 1 means "one level of directory", 2 means "two levels"... This option can speed up Cache_Lite only when you have many thousands of cache file. Only specific benchs can help you to choose the perfect value for you. Maybe, 1 or 2 is a good start.
$_hashedDirectoryUmask	integer	Umask for hashed directory structure
$_id	string	Current cache id
$_lifeTime	integer	If null, the cache is valid forever.
$_memoryCaching	boolean	NB : There is no lifetime for memory caching !
$_memoryCachingArray	array	Memory caching array
$_memoryCachingCounter	integer	Memory caching counter
$_memoryCachingLimit	integer	Memory caching limit
$_onlyMemoryCaching	boolean	Enable / Disable "Only Memory Caching" (be carefull, memory caching is "beta quality")
$_pearErrorMode	integer	(see PEAR doc)
$_readControl	boolean	If enabled, a control key is embeded in cache file and this key is compared with the one calculated after the reading.
$_readControlType	boolean	Available values are : 'md5' for a md5 hash control (best but slowest) 'crc32' for a crc32 hash control (lightly less safe but faster, better choice) 'strlen' for a length only test (fastest)
$_refreshTime	integer	Timestamp of the last valid cache
$_writeControl	boolean	Enable write control will lightly slow the cache writing but not the cache reading Write control can detect some corrupt cache files but maybe it's not a perfect control
