## Interface Node

- All Known Implementing Classes:
    `ASTArray`, `ASTBlock`, `ASTBoolScalar`, `ASTDirective`, `ASTExpression`, `ASTFloatScalar`, `ASTIfElse`, `ASTIntScalar`, `ASTMethod`, `ASTStringScalar`, `ASTText`, `ASTVariable`, `IdentifierNode`, `ScalarNode`, `SimpleNode`

      public interface Node

  All AST nodes must implement this interface. It provides basic machinery for constructing the parent and child relationships between nodes.

    Modifier and Type | Method | Description
    --- | --- | ---
    `void` | `evaluate​(Context context)` |
    `void` | `jjtAddChild​(Node n, int i)` | This method tells the node to add its argument to the node's list of children.
    `Node` | `jjtGetChild​(int i)` | This method returns a child node.
    `int` | `jjtGetNumChildren()` | Return the number of children the node has.
    `Node` | `jjtGetParent()` |

- - ### Method Detail

    - #### jjtSetParent

          void jjtSetParent​(Node n)

      This pair of methods are used to inform the node of its parent.

    - #### jjtGetParent

          Node jjtGetParent()

    - #### jjtAddChild

          void jjtAddChild​(Node n,
                           int i)

      This method tells the node to add its argument to the node's list of children.

    - #### jjtGetChild

          Node jjtGetChild​(int i)

      This method returns a child node. The children are numbered from zero, left to right.

    - #### jjtGetNumChildren

          int jjtGetNumChildren()

      Return the number of children the node has.

    - #### evaluate

          void evaluate​(Context context)
