`public`	# `__construct( string $cachedir = NULL, string $cachegroup = NULL, string $cacheprefix = NULL )` Constructor to create an instance of this class. Constructor to create an instance of this class. Parameters `$cachedir` `string` $cachedir [optional] Directory to cache files `$cachegroup` `string` $cachegroup [optional] Subdirectory to cache files `$cacheprefix` `string` $cacheprefix [optional] Prefixname to add to cached files
`public mixed`	# `enable( boolean $enable = NULL )` Get/Set the flag to enable caching. Get/Set the flag to enable caching. Parameters `$enable` `boolean` $enable [optional] True to enable caching or false Returns `mixed` Enable flag or void
`public mixed`	# `debug( boolean $debug )` Get/Set the flag to debug cache object (prints out miss/hit state with execution time). Get/Set the flag to debug cache object (prints out miss/hit state with execution time). Parameters `$debug` `boolean` $debug True to activate debugging or false. Returns `mixed` Debug flag or void
`public \|string`	# `htmlComment( boolean $htmlcomment )` Get/Set flag to print out cache info as html comment. Get/Set flag to print out cache info as html comment. Parameters `$htmlcomment` `boolean` $htmlcomment True debugging or false. Returns `\|string` Htmlcomment flag or void
`public mixed`	# `lifetime( integer $seconds = NULL )` Get/Set caching lifetime in seconds. Get/Set caching lifetime in seconds. Parameters `$seconds` `integer` $seconds [optional] New Lifetime in seconds Returns `mixed` Actual lifetime or void
`public`	# `infoTemplate( string $template )` Get/Set template to use on printing the chache info. Get/Set template to use on printing the chache info. Parameters `$template` `string` $template Template string including the '%s' format definition.
`public`	# `addOption( string $name, string $option )` Add option for caching (e.g. $_GET,$_POST, $_COOKIE, ...). Add option for caching (e.g. $_GET,$_POST, $_COOKIE, ...). Used to generate the id for caching. Parameters `$name` `string` $name Name of option `$option` `string` $option Value of option (any variable)
`public string`	# `getInfo( )` Returns information cache hit/miss and execution time if caching is enabled. Returns information cache hit/miss and execution time if caching is enabled. Returns `string` Information about cache if caching is enabled, otherwise nothing.
`protected boolean\|string`	# `_start( )` Starts the cache process. Starts the cache process. Returns `boolean\|string`
`public`	# `start( integer $iPageStartTime = NULL )` Handles PEAR caching. Handles PEAR caching. The script will be terminated by calling die(), if any cached content is found. Parameters `$iPageStartTime` `integer` $iPageStartTime [optional] Optional start time, e.g. start time of main script
`public`	# `end( )` Handles ending of PEAR caching. Handles ending of PEAR caching.
`public`	# `removeFromCache( )` Removes any cached content if exists. Removes any cached content if exists. This is nesessary to delete cached articles, if they are changed on backend.
`protected`	# `_initFileCache( )` Creates one-time a instance of PEAR cache output object and also the unique id, if propery $this->_oPearCache is not set. Creates one-time a instance of PEAR cache output object and also the unique id, if propery $this->_oPearCache is not set.
`protected`	# `_raiseEvent( string $name )` Raises any defined event code by using eval(). Raises any defined event code by using eval(). Parameters `$name` `string` $name Name of event to raise
`protected float`	# `_getMicroTime( )` Returns microtime (UNIX timestamp), used to calculate time of execution. Returns microtime (UNIX timestamp), used to calculate time of execution. Returns `float` Timestamp
