public class Peripheral

extends Peripheral

Creates inputs in one SensoryArea that projects to neuroids in 3 input Areas. Inputs are represented by SensoryNeuroids.

Introduces event hooks to enable inputs to be presented at predefined times. Created: Mon Dec 11 02:52:07 2000 Modified: $Date: 2002/10/30 04:42:54 $

Method Detail

initEvents

void initEvents()

Sets the eventIterator to first position.

eventIterator, getNext()

getNext

final void getNext()

Iterates to next event. Events are ordered according to time of occurrance.

See Also:

eventIterator, nextTime

eventsAtThisTime

protected void eventsAtThisTime()

If nextTime is reached, call job(). For all registered events, pop and check for if its time has come.

Specified by:

eventsAtThisTime in class Peripheral

createSensoryInputs

final void createSensoryInputs()

Creates sensoryAreas that hold sensoryNeuroids. Neuroids can be indirectly reached from the areas.

testOneInput

void testOneInput()

Fire one input in sensory area.

fireObjectInArea

void fireObjectInArea(int inputArea,
                      int offset)

Deprecated. See methods in StatisticalInputSequence.java

Fires the sensory neuroid attached to the given input area.

Parameters:

inputArea - an int value

offset - an int value

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
                        ClassNotFoundException

For serialization support.

Parameters:

in - a java.io.ObjectInputStream value

Throws:

IOException - if an error occurs

ClassNotFoundException - if an error occurs
