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.

Static Public Member Functions

static void cat_files (const char *, const Ref< KeyVal > &, std::ostream &o)
This is like the ParsedKeyVal(const char*,const Ref<KeyVal>&) ctor, but writes the contents of the files to the given ostream.

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

static void sc::ParsedKeyVal::cat_files (const char *, const Ref< KeyVal > &, std::ostream & o) [static]

This is like the ParsedKeyVal(const char*,const Ref<KeyVal>&) ctor, but writes the contents of the files to the given ostream.

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.

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.

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).
