Hello Everyone,



I am a beginner in Openfoam programming and I am trying to understand these lines of code.



psiReactionThermo& thermo = reaction->thermo();



basicMultiComponentMixture& composition = thermo.composition();


What I can not understand is the usage of & and the -> in the codeline.



1. Does & call some functionality thermo of class psiReactionThermo. Or is it defining some kind of variable named thermo and then initializing it with reaction?


2. Further, what does the -> mean?



Could somebody share what they mean?
