int startIndex = ctx.start.getStartIndex();
int stopIndex = ctx.stop.getStopIndex();
It does tell me the index from where the block starts and ends.
However, I cannot do the same for its children, e.g. these are the
children of an If-Else statement:
if
(x==5)
{System.out.println("one");}
else
{System.out.println("other one");}
How can I know the Index of "else", there is no getStartIndex() or it's equivalent
