Detailed Description

Declares the DtRunnable class for defining a object that can be run in a thread.

DtRunnable is the defined interface for an object that can be run in a thread. To create a runnable class extend the DtRunnable class and implement the run function. It is important for code that can take considerable time to query the timeToStop() function in all loops, especially infinite loops. There is no safe way to terminate a thread thus to write multi-threading code it is important to allow the controlling thread to safely terminate a child thread.
