13 // //
14 // Class representing a value coming from the interpreter. Its main use case //
15 // is to TCallFunc. When TCallFunc returns by-value, i.e. a temporary //
16 // variable, its lifetime has to be extended. TInterpreterValue provides a //
17 // way to extend the temporaries lifetime and gives the user to control it. //
18 // //
19 // The class needs to be derived from for the actual interpreter, //
20 // see TClingValue. //
