Once the algorithm has been written and integrated into LINK's C++
libraries, programmers will be able to use it to build new C++ programs;
however, the real power of LINK is its computing environment, so new
algorithms should be wrapped into the latter so that they can be called
from the command-line and graphical interfaces. Example wrappers are
shown above in Figures
and
,
and a similar wrapper should be written for our new algorithm. Since
we are adding a fundamental graph algorithm (as opposed to a graph generating
or layout algorithm), its wrapper belongs in the
$LINK\_BASE/src/algorithm/manualSTkWrappers
directory.
Once the file is there, we must update the Make.algorithmWrappers
file to include our new wrapper file in the ``SOURCES.cpp'' macro.
The wrapper file must contain a function to create the new STk commands
which will call our algorithm (for example, see the function called
gen_Random_Wrapper() in Figure
. We
must now arrange for this function to be called. This is done by editing
the file $LINK\_BASE/src/wrappers/algorithmSTkInit.cpp
to make the
appropriate call. This file simply contains prototypes for and calls to
each wrapper generating function. Figure
shows the contents of this file at the time of this writing.

algorithmSTkInit.cpp

The functions STk_algorithm_init() and STk_algorithm_cleanup
are called at the beginning and ending, respectively of a LINK session.
