public interface Expr
An Expr
represents any Java expression. All expressions
must be subtypes of Expr.

void printSubExpr(Expr expr, boolean associative, CodeWriter w, PrettyPrinter pp)
expr
based on its precedence and the precedence of this expression.
If the sub-expression has the same precedence as this expression
we parenthesize if the sub-expression does not associate; e.g.,
we parenthesis the right sub-expression of a left-associative
operator.
void printSubExpr(Expr expr, CodeWriter w, PrettyPrinter pp)
expr
based on its precedence and the precedence of this expression.
This is equivalent to printSubexpr(expr, true, w, pp)
