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 occurring when scanning a `svc.conf' file and activating an ACE_Task, for example, as a result of processing the directives in that file. */ class ACE_Svc_Conf_Param { public: enum SVC_CONF_PARAM_TYPE { / The lexer will scan a file containing one or more directives. SVC_CONF_FILE,

/ The lexer will scan a string containing a directive. SVC_CONF_DIRECTIVE };

/ Constructor ACE_Svc_Conf_Param (ACE_Service_Gestalt *gestalt, FILE *file) : type (SVC_CONF_FILE), yyerrno (0), yylineno (1), buffer (0), obstack (), config (gestalt) { source.file = file; }

/ Constructor ACE_Svc_Conf_Param (ACE_Service_Gestalt *gestalt, const ACE_TCHAR *directive) : type (SVC_CONF_DIRECTIVE), yyerrno (0), yylineno (1), buffer (0), obstack (), config (gestalt) { source.directive = directive; }

~ACE_Svc_Conf_Param () { ace_yy_delete_buffer (this->buffer); }

public: union { / FILE stream from which directives will be scanned and parsed. FILE *file;

/ String containing directive that will be scanned and parsed. const ACE_TCHAR *directive; } source;

/ Discriminant use to determine which union member to use. SVC_CONF_PARAM_TYPE type;

/ Keeps track of the number of errors encountered so far. int yyerrno;

/ Keeps track of the current line number for error-handling routine. int yylineno;

/ Lexer buffer that corresponds to the current Service / Configurator file/direct scan. ace_yy_buffer_state *buffer;

/ Obstack used for efficient memory allocation when / parsing/scanning a service configurator directive. ACE_Obstack_T<ACE_TCHAR> obstack;

/ A reference to the configuration ACE_Service_Gestalt *config; };

Parameter that is passed down to the yyparse() function, and eventually to yylex(). #define ACE_YYPARSE_PARAM
