Examples of org.cishell.framework.algorithm.Algorithm

org.cishell.framework.algorithm.Algorithm
A class which executes some arbitrary code and optionally returns any data produced. What happens when the execute method is run is entirely up to the Algorithm developer. Algorithms should be primed with whatever data is needed, usually by its associated {@link AlgorithmFactory}, before execution. This allows an Algorithm to be set up, then scheduled for later execution. @author Bruce Herr (bh2@bh2.net)
