Field index of TParser

Method index of TParser

Fields

This collection holds name of input files.

char *InFile

Name of the actual input file.

TIndex ActualInFile

Index of actual input file in the collection.

int ErrorCode

Error code of parser.

long LineNum

Number of line where error has occured. Name of the file can be found in InFile field.

bool ShowDt

Data structures should be reported after parsing.

bool ShowGRP

GRP file should be generated after parsing.

bool Html

If this field is true the parser produces debugging information in HTML format. It is false by default.

bool Debug

If this field is true the parser produces debugging information during parsing. It is false by default.

char *GifsRoot

URL which defines directory where GIF pictures can be found. For example: "http://www.cpc.wmin.ac.uk/~drotos/gifs". This parameter is used when parser makes debugging information in HTML form.

char DealParam

Value of this filed specifies behavior of the parser when it finds redefinition of a parameter in a parameter group. If the value is 'a' it appends values to the excisting parameter, if the value is 'o' then it deletes old parameter and creates a new one, and if the value is 'e' (or other) then it aborts its operation and prints out an error message.

PprsAppColl Apps

Collection of applications.

Methods

Constructor of the parser object class.

virtual ~TParser(void)

Destructor of the parser object class.

Initialization

This method contains virtual method calls that should be done during constructing of the object, so it must be called immediately after parser object had been created.

virtual PprsAppColl MakeAppColl(void)

This method makes a collection to store applications. If you are going to use your own type of application collection you have to override this method.

void AddInFile(char *FileName)

This method adds FileName file to the list of input files.

Parsing

This method parses every files on input file collection. Informations collected from files are merged together. Return value of this function is error code of the parser. It is 0 if files are parsed successfully.

bool NextInFile(void)

Used intenally by the parser.

virtual PprsProcGroup make_ProcGroup(int type, char *name, int id)

This method is used by the parser to make a new process group object. Parameters are the parsed elements: type can be tokPROCGROUP or tokFARM; name is the name of the process group and id is a unique identification number in the GRP file.

Reports

virtual void ShowData(FILE *To)

This method produces a report about data structures built by the parser in file To.

virtual void WriteGRP(FILE *To)

This method writes parsed information to GRP file To.
