<div class="textblock"><p>This class provides some useful global variables. They are not static, instead there exists a global Globs object to make it easy to use different <a class="el" href="classGlobals.html" title="some useful pointers that should be global ">Globals</a> objects during one execution (this is necessary for some unit-tests).</p>
<p>The <a class="el" href="classGraph.html" title="a graph constructed from a cover file and a message to be embedded ">Graph</a> constructor as well as the <a class="el" href="classCvrStgFile.html" title="a cover-/stego-file ">CvrStgFile</a> constructor write itself into the Globs object. Doing this so early is necessary because the construction of a <a class="el" href="classGraph.html" title="a graph constructed from a cover file and a message to be embedded ">Graph</a> or <a class="el" href="classCvrStgFile.html" title="a cover-/stego-file ">CvrStgFile</a> object might already need a correctly set Globs object.</p>
<p>During one "normal" (i.e. non-unit-test) execution of steghide only one <a class="el" href="classGlobals.html" title="some useful pointers that should be global ">Globals</a> object will be used, namely the one created in <a class="el" href="src_2main_8cc.html#a0ddf1224851353fc92bfbff6f499fa97">main()</a>, filled in the <a class="el" href="classGraph.html" title="a graph constructed from a cover file and a message to be embedded ">Graph</a> and the <a class="el" href="classCvrStgFile.html" title="a cover-/stego-file ">CvrStgFile</a> constructor and stored at the Globs pointer.</p>
<p>The main purpose of making these variables global is to save memory in classes that are small but used in large numbers (e.g. *SampleValue,...). Using static pointers in these classed would be too chaotic to reset for the unit tests and non-static pointers would need too much memory. </p>
