Our plan was to develop a programm that is very flexibel and easy to expand. So most of our code is build modularly. PTF is divided into three chunks. These are:
This is the base of PTF. It contains the class PtfCore as kind of backbone. This class keeps references to all other parts. Exspecially book keeping for Tasks (Task), Sequences (Sequence) with its iterator (SequenceIterator) and all input devices (InputDevice) is done here. Furthermore the different experiment records (TaskRecord, ReactionRecord) and logs (Log) are acessed via this backbone. Last but not least the scheduler class (Scheduler) and reaction handler (ReactionHandler) are included.
This class is the main entry point of every PTF application.
These classes are used for displaying things (Graphic), playing audio samples (Audio), time measurement (Clock) and setting trigger signals on ports (Parallel).
The class InputDevice is a base for all defined methods of input.
