Class DeadCodeElimination.FindBreakContinueStatementsVisitor

java.lang.Object

com.google.gwt.dev.jjs.ast.JVisitor

com.google.gwt.dev.jjs.impl.DeadCodeElimination.FindBreakContinueStatementsVisitor

Enclosing class:

DeadCodeElimination

public static class DeadCodeElimination.FindBreakContinueStatementsVisitor
extends JVisitor

Examines code to find out whether it contains any break or continue statements. TODO: We could be more sophisticated with this. A nested while loop with an unlabeled break should not cause this visitor to return false. Nor should a labeled break break to another context.
