# There is a bug in the next line.  $searchParameters != {} will always return true, because {} is creating
# a new hash reference on the fly, and the inequality operater is comparing the memory location of it
# to the memory location of $searchParameters, and they will always be different. 
# This means that the following code will always get executed as long as $nodes is defined.
# I'm leaving it there because it has always been there, and although I'm sure it was originally meant to
# mean %$searchParameters (essentially "is this hash not empty"), I'm afraid to change it.

//What is this?
public bool IsReusable

    get{return false;}
}

Case 1:

   break;
   ...
//I don't want do do this but [my coworker] says it's part of the code standard
