Class SimpleTreeVisitorES5_1<R,​P>

java.lang.Object
jdk.nashorn.api.tree.SimpleTreeVisitorES5_1<R,​P>
Type Parameters:
R - the return type of this visitor's methods. Use Void for visitors that do not need to return results.
P - the type of the additional parameter to this visitor's methods. Use Void for visitors that do not need an additional parameter.
All Implemented Interfaces:
TreeVisitor<R,​P>

public class SimpleTreeVisitorES5_1<R,​P>
extends Object
implements TreeVisitor<R,​P>
Deprecated, for removal: This API element is subject to removal in a future version.
Nashorn JavaScript script engine and APIs, and the jjs tool are deprecated with the intent to remove them in a future release.
A simple implementation of the TreeVisitor for ECMAScript edition 5.1.

The visit methods corresponding to ES 5.1 language constructs walk the "components" of the given tree by calling accept method passing the current visitor and the additional parameter.

For constructs introduced in later versions, visitUnknown is called instead which throws UnknownTreeException.

Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with @Override will help ensure that methods are overridden as intended.

      public R visitUnknown​(Tree node, P p)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Visit unknown expression/statement tree. This fallback will be called if new Tree subtypes are introduced in future. A specific implementation may throw {unknown tree exception if the visitor implementation was for an older language version.
      Specified by:
      visitUnknown in interface TreeVisitor<R,​P>
      Implementation Requirements:
      The default implementation of this method in SimpleTreeVisitorES5_1 will always throw UnknownTypeException. This behavior is not required of a subclass.
      Parameters:
      node - node being visited
      p - extra parameter passed to the visitor
      Returns:
      abnormal return by throwing exception always
      Throws:
      UnknownTreeException - a visitor implementation may optionally throw this exception
