Detailed Description

a factory used to create PrinterList instances to be used by a PropertyPrinter instance.

PrinterList classes are used to print out property values of a particular type. Typically, a default PrinterFactory is filled with support for the common primitive types and type classes that are important for logging. Other types can be supported by providing an implementation of PrinterList and corresponding iterator that support the type as well as an implementation of a factory function that creates a pointer to the specialized PrinterList. A pointer to the factory function is what one registers with this general PrinterFactory.

PrinterFactory::factoryFuncPtr defines the form of the factory function:

*   PrinterList* (*makePrinterList)(const PropertySet&, const string&)
* 

See PrinterList for more details about supporting a new type.
