      Specified by:
      isEqualTo in interface Node<Field>
      Parameters:
      o - the other node to compare to

      public String toString()
      Overrides:
      toString in class Object
    • accept

      public TraversalControl accept(TraverserContext<Node> context, NodeVisitor visitor)
      Description copied from interface: Node
      Double-dispatch entry point. A node receives a Visitor instance and then calls a method on a Visitor that corresponds to a actual type of this Node. This binding however happens at the compile time and therefore it allows to save on rather expensive reflection based instanceOf check when decision based on the actual type of Node is needed, which happens redundantly during traversing AST. Additional advantage of this pattern is to decouple tree traversal mechanism from the code that needs to be executed when traversal "visits" a particular Node in the tree. This leads to a better code re-usability and maintainability.
      Specified by:
      accept in interface Node<Field>
      Parameters:
      context - TraverserContext bound to this Node object
      visitor - Visitor instance that performs actual processing on the Nodes(s)
      Returns:
      Result of Visitor's operation. Note! Visitor's operation might return special results to control traversal process.
