Detailed Description

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

This is intended for internal use within ACE service configuration framework only.

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.
