object Log &singleton(

Attempts to return a reference to a concrete Log instance of type $handler, only creating a new instance if no log instance with the same parameters currently exists.

You should use this if there are multiple places you might create a logger, you don't want to create multiple loggers, and you don't want to check for the existance of one each time. The singleton pattern does all the checking work for you.

You MUST call this method with the $var = &Log::singleton() syntax. Without the ampersand (&) in front of the method name, you will not get a reference, you will get a copy.

Return: The newly created concrete Log instance, or null on an error.
Since: Log 1.0
Access: public

Parameters:

string	`$handler`	—	The type of concrete Log subclass to return. Attempt to dynamically include the code for this subclass. Currently, valid values are 'console', 'syslog', 'sql', 'file', and 'mcal'.
string	`$name`	—	The name of the actually log file, table, or other specific store to use. Defaults to an empty string, with which the subclass will attempt to do something intelligent.
string	`$ident`	—	The identity reported to the log system.
array	`$conf`	—	A hash containing any additional configuration information that a subclass might need.
int	`$level`	—	Log messages up to and including this level.

string stringToPriority(
