Hi,
I noticed in generated ANTLR3 grammars, that certain elements look like
this:
name ...
: ...
{
ei.leaveContext(false);
}
;
now the leaveContextmethod looks like this:
public void leaveContext(boolean leave) {
if(leave) currentContext = currentContext.parent();
}
So I cannot see the point of calling leaveContext with false. So I wonder,
what is the reason for this (Or is it something historical)?
regards,
Thibault

It is something historical ;-).
