> This is the current proposed patch for the upcoming JEP 394, for pattern > matching for instanceof. > > A summary of changes: > -making the feature permanent (non-preview) > -making the binding variables non-final (as per current specification > proposal) > -producing a compile-time error for the case where the expression's type is a > subtype of the type test pattern's type (as per current specification > proposal) > -changing the AST structure so that the binding variable has a VariableTree > in the AST. BindingPatternTree is preserved and encloses the VariableTree. > The reason is better consistency in the API, with nodes like CatchTree, > EnhancedForLoop Tree, etc. > > This change will not be integrated until JEP 394 is targetted.
