Detailed Description

KeywordHandler is a class that associates a string, the keyword, with a function pointer for creating objects of a type corresponding to that keyword. It is used by Factory to to manage creating layers, connections, etc., within a HyPerCol. It is generally not used except internally by Factory.

As an example, after creating a KeywordHandler with the statement

KeywordHandler * kwh = new KeywordHandler("HyPerLayer", createHyPerLayer);

(the function createHyPerLayer is defined in layers/HyPerLayer.hpp), one can insert a new HyPerLayer called "layer" into a given HyPerCol with the statement.

kwh->create("layer", hc);
