"""
|

|
tileset.py contains the TileSet class, and in general, routines that manage a
|
|
set of output tiles corresponding to a requested rendermode for a world. In
|
|
general, there will be one TileSet object per world per rendermode requested by
|
|
the user.
|
|
|
|
The TileSet class implements the Worker interface. This interface has the
|
|
following methods:
|
|
|
|
do_preprocessing()
|
|
This method is called before iterate_work_items(). It should do any work
|
|
that needs to be done prior to iterate_work_items(). It is not called for
|
|
instances that will not have iterate_work_items() called.
|
|
|
|
get_num_phases()
|
|
This method returns an integer indicating how many phases of work this
|
|
worker has to perform. Each phase of work is completed serially with the
|
|
other phases... all work done by one phase is done before the next phase is
|
|
started.
|
|
|
|
iterate_work_items(phase)
|
|
Takes a phase number (a non-negative integer). This method should return an
|
|
iterator over work items. The work items can be any pickelable object; they
|
|
are treated as opaque by the Dispatcher. The work item objects are passed
|
|
back in to the do_work() method (perhaps in a different, identically
|
|
configured instance)
|
|
|
|
do_work(workobj)
|
|
Does the work for a given work object. This method is not expected to
|
|
return anything, so the results of its work should be reflected on the
|
|
filesystem or by sending signals.
|
|
|
|
