Member Function Documentation

void Light::parseSymbol (  Token &    t, ObjectFile &    file )  [virtual]

Reads a single parameter sections inside the body of the object description. Each object has a set of parameter names associated with it, called symbols. Symbols are declared inside the createSymbols method. The method parseSymbol expects the Token t to be such a symbol and reads the corresponding parameters. Unknown symbols are passed to its super class. Parameters: t  Token that is the current parameter symbol. file  ObjectFile from which to read. Precondition: The file is opened for reading and is positioned just after the parameter name. Postcondition: The parameter section is read including the terminating semicolon (';'). Reimplemented from DynamicObject.

void Light::writeParams (  ostream &    stream )  [virtual]

Writes all parameter sections inside the body of the object description. This method writes all object parameters to ostream. Inhereting classes will always call super::writeParams(). Parameters: stream  ostream to which to write. Precondition: stream is opened for writing. Postcondition: All object parameters are written. Reimplemented from DynamicObject.
