Class BiDiBNodeInitializer

java.lang.Object

jmri.jmrix.bidib.BiDiBNodeInitializer

All Implemented Interfaces:

Runnable

public class BiDiBNodeInitializer
extends Object
implements Runnable

This class initializes or deinitializes a BiDiB node when it is found on system startup or if it is discovered or lost while the system is running.\ The real work is done in its own thread and from a node queue. Initializing is a time consuming process since a lot of data is read from the node.
