      public Node getOperand()

    • getBindingVariable

      @Deprecated public @Nullable LocalVariableNode getBindingVariable()
      Deprecated.
      Use getPatternNode() or getBindingVariables() instead.
      Returns the binding variable for this instanceof, or null if one does not exist.
      Returns:
      the binding variable for this instanceof, or null if one does not exist

      Return all the binding variables in this instanceof.
      Returns:
      all the binding variables in this instanceof

    • getPatternNode

      public @Nullable Node getPatternNode()
      Returns the pattern for this instanceof, or null if one does not exist.
