Method Detail

executingJob

boolean executingJob(java.lang.Object source,
                     boolean inProgress)

Called by the object doing the lengthy job to notify its invoker that it is still working.

Parameters:

source - the object doing the lengthy job

inProgress - true if the source is still working; false if the job has just been finished.

executingJob(source, false) is garanteed to be called once even if the job was aborted and an exception (other than JobCanceledException, see below) thrown.

Returns:

false if the invoker wishes the job to be canceled; true otherwise.

Most sources do not support job cancelation. Those who support this feature will implement it by throwing a JobCanceledException.
