Class TaskFactory

java.lang.Object
  com.massimo.tools.scriptrunner.TaskFactory

public final class TaskFactory
extends Object

Factory class for Tasks, based on the type or class attributes. If type is set, the class is assumed to be of the form <type>Task. The control sub-package Task implementations are recognized, but all others must be in the work sub-package. Custom tasks can be used by specifying the class attribute, with a value of the full class name, e.g. com.automagicsoftware.tasks.DeleteFileTask Setting the allSerial property changes Parallel tasks into Serial. This is useful for debugging.
