Description

The anonymous process has an infinite loop which waits for input to become available on any of the out Channels using the Alternative class. Upon receiving the Object the Object and the Channel number are output.

The user can add and remove Channels from the DynamicDelta using the interface.

The purpose of this test is to check to see if adding and removing Channels from a DynamicDelta functions correctly.

NOTE: The code for this Applet is not a good example of developing programs using the library, it has been designed to allow the component to be tested without depending on more classes from the library than is necessary.

DynamicDeltaTest()

actionPerformed(ActionEvent)

If the component which generated was the add Button the current selected item from the inactiveChannels list will obtained.

getAppletInfo()

returns the name and author of the Applet.

init()

Initialises the main AppletTest Applet.

 public DynamicDeltaTest()

 public void init()

Initialises the main AppletTest Applet. This method creates the visual components and the CSP process network and starts it running.

Overrides:

init in class Applet

 public void actionPerformed(ActionEvent e)

If the component which generated was the add Button the current selected item from the inactiveChannels list will obtained. If it is not null the item will be removed from inactiveChannels, added to activeChannels the the Channel with that key in the channels HashTable will be sent down the configure Channel.

If the component which generated was the remove Button the current selected item from the activeChannels list will obtained. If it is not null the item will be removed from activeChannels, added to inactiveChannels the the Channel with that key in the channels HashTable will be sent down the configure Channel.

Parameters:

e - The ActioneEvent

 public String getAppletInfo()

returns the name and author of the Applet.

Overrides:

getAppletInfo in class Applet
