sc::ParsedKeyVal(3)		     MPQC		   sc::ParsedKeyVal(3)

NAME
       sc::ParsedKeyVal	- Converts textual information into keyword/value
       assocations.

SYNOPSIS
       #include	<keyval.h>

       Inherits	sc::StringKeyVal.

   Public Member Functions
       ParsedKeyVal ()
	   Create an empty ParsedKeyVal.
       ParsedKeyVal (const char	*file)
	   Parse the given input file.
       ParsedKeyVal (std::istream &s)
	   Read	input from s.
       ParsedKeyVal (IPV2 *)
	   Use the given IPV2* object.
       ParsedKeyVal (const char	*, const Ref< KeyVal > &)
	   This	ctor is	given a	string which is	used to	form keywords that are
	   sought in the keyval	argument.
       ~ParsedKeyVal ()
	   Cleanup, deleting the IPV2 object.
       void read (const	char *)
	   Read	input data from	the given filename.
       void read (std::istream &)
	   Read	input data from	the given stream.
       void parse_string (const	char *)
	   Read	input data from	the given string.

       Overrides of parent members.
       See parent class	documentation.

	   const char *	stringrep (const char *)
	       Returns the string representation of the	value assigned to key.
	   const char *	classname (const char *)
	       Returns the name	of the exact class of the object at the
	       keyword.
	   const char *	truekeyword (const char	*)
	       Returns a string	which is the actual keyword if some sort of
	       variable	substitution takes place (needed to make multiple
	       references to the same object work in input files).
	   void	errortrace (std::ostream &fp=ExEnv::err0())
	       Write a message to fp describing	the error.
	   void	dump (std::ostream &fp=ExEnv::err0())
	       Write a message to fp describing	the error.
	   void	print_unseen (std::ostream &fp=ExEnv::out0())
	       Print keywords that were	never looked at, if possible.
	   int have_unseen ()
	       Return 1	if there were unseen keywords, 0 if there are none, or
	       -1 this keyval doesn't keep track of unseen keywords.
       virtual const char * stringrep (const char *key)=0
	   Returns the string representation of	the value assigned to key.
       virtual const char * classname (const char *)
	   Returns the name of the exact class of the object at	the keyword.
       virtual const char * truekeyword	(const char *)
	   Returns a string which is the actual	keyword	if some	sort of
	   variable substitution takes place (needed to	make multiple
	   references to the same object work in input files).

Detailed Description
       Converts	textual	information into keyword/value assocations.

       The parsing is done with	an IPV2	object.	The keyval for more
       information on the input	format.

Constructor & Destructor Documentation
   sc::ParsedKeyVal::ParsedKeyVal (IPV2	*)
       Use the given IPV2* object. The new ParsedKeyVal	takes wnership of the
       passed IPV2 object.

   sc::ParsedKeyVal::ParsedKeyVal (const char *, const Ref< KeyVal > &)
       This ctor is given a string which is used to form keywords that are
       sought in the keyval argument. The associated values are	used to
       construct file names that are used to initialize	the ParsedKeyVal. The
       keywords	sought are string'dir' for the directory prefix	and
       string'files' for an array of file names.

Member Function	Documentation
   const char *	sc::ParsedKeyVal::classname (const char	*) [virtual]
       Returns the name	of the exact class of the object at the	keyword. If no
       classname is assigned then 0 is returned.

       Reimplemented from sc::StringKeyVal.

   void	sc::ParsedKeyVal::dump (std::ostream & fp = ExEnv::err0()) [virtual]
       Write a message to fp describing	the error.

       Reimplemented from sc::StringKeyVal.

   void	sc::ParsedKeyVal::errortrace (std::ostream & fp	= ExEnv::err0())
       [virtual]
       Write a message to fp describing	the error.

       Reimplemented from sc::StringKeyVal.

   int sc::ParsedKeyVal::have_unseen ()	[virtual]
       Return 1	if there were unseen keywords, 0 if there are none, or -1 this
       keyval doesn't keep track of unseen keywords.

       Reimplemented from sc::KeyVal.

   void	sc::ParsedKeyVal::print_unseen (std::ostream & fp = ExEnv::out0())
       [virtual]
       Print keywords that were	never looked at, if possible.

       Reimplemented from sc::KeyVal.

   const char *	sc::ParsedKeyVal::stringrep (const char	* key) [virtual]
       Returns the string representation of the	value assigned to key.

       Implements sc::StringKeyVal.

   const char *	sc::ParsedKeyVal::truekeyword (const char *) [virtual]
       Returns a string	which is the actual keyword if some sort of variable
       substitution takes place	(needed	to make	multiple references to the
       same object work	in input files).

       Reimplemented from sc::StringKeyVal.
