Constructor Detail

### ASTSetDirective

    public ASTSetDirective(int id)

### ASTSetDirective

    public ASTSetDirective(Parser p,
                           int id)

Method Detail

### jjtAccept

    public java.lang.Object jjtAccept(ParserVisitor visitor,
                                      java.lang.Object data)

  Accept the visitor.
  Overrides:
    `jjtAccept` in class `SimpleNode`

### init

    public java.lang.Object init(InternalContextAdapter context,

                          throws java.lang.Exception

  simple init. We can get the RHS and LHS as the the tree structure is static
  Overrides:
    `init` in class `SimpleNode`

### render

                   throws java.io.IOException,
                          MethodInvocationException

  puts the value of the RHS into the context under the key of the LHS
  Overrides:
    `render` in class `SimpleNode`

### getLeftHandSide

    private ASTReference getLeftHandSide()

  returns the ASTReference that is the LHS of the set statememt

### getRightHandSide

    private Node getRightHandSide()

  returns the RHS Node of the set statement
