Class StackPrinter.ExpressionPrinter

java.lang.Object

eu.bandm.tools.d2d2.model.MATCH_ONLY_00

eu.bandm.tools.d2d2.base.StackPrinter.ExpressionPrinter

Enclosing class:

StackPrinter

protected static class StackPrinter.ExpressionPrinter
extends SinglePhase

Simply prints expressions, inserting parentheses by priority. COULD PERHAPES be replaced by format generating visitor FIXME !?!? BUT the derived class StackPrinter does additional highlighting for References.
