<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>A problem represents infeasibilities, alerts and warnings in the plan. </p>
<p>Problems are maintained internally by the system. They are thus only exported, meaning that you can't directly import or create problems.<br/>
This class is the pure virtual base class for all problem types.<br/>
The usage of the problem objects is based on the following principles:</p>
<ul>
<li>Problems objects are passive. They don't actively change the model state.</li>
<li>Objects of the <a class="el" href="a00086.html" title="Classes that keep track of problem conditions need to implement this class.">HasProblems</a> class actively create and destroy <a class="el" href="a00134.html" title="A problem represents infeasibilities, alerts and warnings in the plan.">Problem</a> objects.</li>
<li><a class="el" href="a00134.html" title="A problem represents infeasibilities, alerts and warnings in the plan.">Problem</a> objects are managed in a 'lazy' way, meaning they only are getting created when the list of problems is requested by the user.<br/>
During normal planning activities we merely mark the planning entities that have changed, so we can easily pick up which entities to recompute the problems for. In this way we can avoid the cpu and memory overhead of keeping the problem list up to date at all times, while still providing the user with the correct list of problems when required.</li>
<li>Given the above, Problems are lightweight objects that consume limited memory. </li>
</ul>
