Detailed Description

An instance of this object will be passed down to the yyparse() and yylex() functions.

This class retains the state for a given parse/scan. It primarily makes it possible to hold the static object lock in the scanner for as short a period of time as possible. The resulting finer grained locking prevents deadlocks from occuring when scanning a `svc.conf' file and activating an ACE_Task, for example, as a result of processing the directives in that file.
