class MadParser : public Parser

(Return to index)

The default parser for MAD-9.

The parser reads a command name and keyword and looks up the keyword in the directory. If it finds an object, it makes a clone with the name read and calls the parser for the cloned object. If that parser succeeds, it calls the clone's execute() function. As required, it first updates the data structure to ensure that everything is up-to-date. Optionally, command execution is also traced.
