Classpublic class IOPort

A simulation of the Input/Output port which is used for the communication between the various electronic devices.
The IO Ports could be used for either input or output.
Several IO Ports could be connected to each other to share their states.

[read-only] A list of all connected IO Ports
IOPort
  direction : Number
IOPort
  value : Boolean
[read-only] Gets a value of the port, dependin on its direction:
  • if the direction is INPUT, the value of the port is HIGH if and only if the value of the one of the connected OUTPUT ports is HIGH
  • if the direction is OUTPUT, the value is the one set by the high() or low() function by the controller

Constructor detail
IOPort()constructor
public function IOPort(direction:Number)

Create an IO Port with the given direction

Parameters
direction:Number
Method detail
connectPorts()method
public function connectPorts(port:IOPort):void

Connect an IO port to the current port.

NOTE: since every port contains a list of the connected ports connecting two ports of the same direction is not allowed due to the danger of an infinite loop.

Parameters
port:IOPort — - target IO Port

Throws
— Error whenever two ports of the same direction are attempted to be connected

Set a value of the output port to LOW
