* QueryLog implements the query_log plugin.
34
* This is our event observer plugin subclass that sits between Drizzle
35
* and logger classes like QueryLoggerFile. This class encapsulates and
36
* manages data associated with the plugin: system variables and incoming
37
* events. The future plan is to have other logger classes, like
38
* QueryLoggerTable or QueryLoggerUDPSocket. So implemeting those should
39
* be easy because this class abstracts plugin data management from actual
40
* logging: it gets events from Drizzle, filters and prepares them, then
41
* sends them to logger classes which only have to log them.
