All Implemented Interfaces:

public class LongRunningReadAction
extends Action

A pathetic example of a background job that simulates reading from the model (though not actually reading anything, only obtaining a read lock). The job simply loops sixty times, sleeping for 500 millis and printing a message, all within the context of a read-only transaction on the editing domain. At each iteration, after sleeping and checking the progress monitor for cancellation, the job yields the editing domain to any other transactions that need to read. Such transactions might include UI refreshes or even other concurrent instances of this job.
