    • value

      public String value()

      Overrides:
      value in class LeafNode<String>
      Returns:
      the string representation of this StringNode, or null if the value is explicitly set to null

    • getValue

      public String getValue()
      Description copied from class: LeafNode
      Subclasses must implement this, in compliance with the rules given in the return tag.
      Specified by:
      getValue in class LeafNode<String>
      Returns:
      the String representation of the node value, or the 'null' object if the node value is null.

    • toString

      public String toString()
      Description copied from class: LeafNode
      Subclasses must implement this, in compliance with the rules given in the return tag.
      Specified by:
      toString in class LeafNode<String>
      Returns:
      the String representation of the node value, or the string "(null)" if the value is null.

      Parameters:
