Detailed Description

An Expression object is used, to store the information needed when running a command of a Session Evaluation of Expression is an asynchroneous process in most cases, so most of the members of this class are not useful directly after its construction. Therefore there are signals indicating, when the Expression goes through the different stages of the Running process. An Expression is never constructed directly, but by using Session::evaluateExpression()
