[antlr-interest] java.tree.g: A way to get parent of primaryExpression?

[rustydstone]

When calculating primary expression, I need somehow to determine the
immediate parent of primary expression. In other words, primary
expression will be calculated differently if the parent is, e.g.,
unary minus or regular minus.

Any ideas? Thanks

expr:	#(QUESTION expr expr expr)
[...]
  |     #(MINUS expr expr)
[...]
  |     #(UNARY_MINUS expr)
  |     #(UNARY_PLUS expr)
  |     primaryExpression
;
