## 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.
  Since:
    4.1

- - ### Method Summary

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and 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()`
    `void` | `jjtSetParent(Node n)` This pair of methods are used to inform the node of its parent.

- - ### 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)
