java.lang.Objectjavafe.ast.ASTNode
javafe.ast.Stmt
javafe.ast.SwitchLabel
Represents a SwitchLabel syntactic unit. If expr is null, then represents the "default" label, otherwise represents a case label.
We infer a default: break at the end of each switch statement that does not contain a default case to simplify translation. Such inferred cases will have their location equal to the location of the closing bracket of the switch statement they are contained in.
