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.
