<H2>Class Description</H2>
createEnd does a lot of specific things that make the data output
objects work. It gets the system time, uses that to fashion a
filename that includes the time, then where necessary it creates
archivers which will later be called on to get readings on the
system and record them.

<A NAME="- drop"></A><H3><A NAME="//apple_ref/occ/instm/Output/drop">drop</A></H3><P>
<CODE>- (void)<B>drop</B>
</CODE><P>
It is necessary to drop the data writing objects in order to make
sure they finish their work.
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- initializeHDFWriter"></A><H3><A NAME="//apple_ref/occ/instm/Output/initializeHDFWriter">initializeHDFWriter</A></H3><P>
<CODE>- (void)<B>initializeHDFWriter</B>
</CODE><P>
In case the Output class is told to write output data and there is
no hdfWriter object yet, then this method will be run. I could not
find another way to make sure that this object was not created unless
the system actually tries to write data. It cannot be done in the
prepareOutputFile method, because that method can be called from the
GUI before the Specialist and World objects exist. Those objects are
necessary to initialize an hdfWriter, as seen in this code.
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- prepareOutputFile"></A><H3><A NAME="//apple_ref/occ/instm/Output/prepareOutputFile">prepareOutputFile</A></H3><P>
<CODE>- <B>prepareOutputFile</B>
</CODE><P>
Because it is possible for users to turn on data writing during a
run of the simulation, it is necessary to have this method which can
initialize the data output files. Each time this is called, it
checks to see if the files have already been initialized. That way
it does not initialize everything twice.
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- setSpecialist:"></A><H3><A NAME="//apple_ref/occ/instm/Output/setSpecialist:">setSpecialist:</A></H3><P>
<CODE>- <B>setSpecialist:</B>(Specialist *)<EM>theSpec</EM>
</CODE><P>
The output object needs to have a reference to a Specialist object, from whom it can gather data on the volume of trade.
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- setWorld:"></A><H3><A NAME="//apple_ref/occ/instm/Output/setWorld:">setWorld:</A></H3><P>
<CODE>- <B>setWorld:</B>(World *)<EM>theWorld</EM>
</CODE><P>
The output object must have a reference to a World object, from which it can get price, dividend, or any other information it wants
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- writeData"></A><H3><A NAME="//apple_ref/occ/instm/Output/writeData">writeData</A></H3><P>
<CODE>- <B>writeData</B>
</CODE><P>
The write data method dumps out measures of the price, dividend, and volume indicators into several formats
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- writeParams:BFAgent:Time:"></A><H3><A NAME="//apple_ref/occ/instm/Output/writeParams:BFAgent:Time:">writeParams:BFAgent:Time:</A></H3><P>
<CODE>- <B>writeParams:</B><EM>modelParam</EM> <B>BFAgent:</B><EM>bfParms</EM> <B>Time:</B>(long int)<EM>t</EM>
</CODE><P>
This flushes a snapshot of the current parameter settings from
both the ASMModelParams and BFAgentParams into a file
