* <h2>Important Note</h2>
*
* This method overrides the BaseType method of the same name and type signature and it
* significantly changes the behavior for all versions of <code>printVal()</code> for this type:
* <b><i> All the various versions of printVal() will only print a value, or a value with
* declaration, if the variable is in the projection.</i></b> <br>
* <br>
* In other words, if a call to <code>isProject()</code> for a particular variable returns <code>
* true</code> then <code>printVal()</code> will print a value (or a declaration and a value).
* <br>
* <br>
* If <code>isProject()</code> for a particular variable returns <code>false</code> then <code>
* printVal()</code> is basically a No-Op. <br>
* <br>
*
* @param os the <code>PrintWriter</code> on which to print the value.
* @param space this value is passed to the <code>printDecl</code> method, and controls the
* leading spaces of the output.
* @param print_decl_p a boolean value controlling whether the variable declaration is printed as
* well as the value.
* @see BaseType#printVal(PrintWriter, String, boolean)
* @see ServerMethods#isProject()
