## Public Member Functions

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).
Debugging.
See the parent class documentation for descriptions of these functions.
virtual void | errortrace (std::ostream &fp=ExEnv::err0())
| Write a message to fp describing the error.
virtual void | dump (std::ostream &fp=ExEnv::err0())
| Write a message to fp describing the error.

## Protected Member Functions

int | key_exists (const char *)
| Ultimately called by exists.
Ref< KeyValValue > | key_value (const char *, const KeyValValue &def)
| Ultimately called by value.

## Detailed Description

StringKeyVal is a base class for KeyVal implementations that store all values in a string format.

These are converted to other data types through KeyValValue.

## Member Function Documentation

virtual const char* sc::StringKeyVal::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 in sc::ParsedKeyVal.

virtual const char* sc::StringKeyVal::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 in sc::ParsedKeyVal.
