Method Detail

### jjtOpen

    void jjtOpen()

  This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.

### jjtClose

    void jjtClose()

  This method is called after all the child nodes have been added.

### 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.

### getImage

    java.lang.String getImage()

### getValue

    java.lang.Object getValue(EvaluationContext ctx)
                              throws javax.el.ELException

  Throws:
    `javax.el.ELException`

### setValue

    void setValue(EvaluationContext ctx,
                  java.lang.Object value)
                  throws javax.el.ELException

  Throws:
    `javax.el.ELException`

### getType

    java.lang.Class getType(EvaluationContext ctx)
                            throws javax.el.ELException

  Throws:
    `javax.el.ELException`

### isReadOnly

    boolean isReadOnly(EvaluationContext ctx)
                       throws javax.el.ELException

  Throws:
    `javax.el.ELException`

### accept

    void accept(NodeVisitor visitor)
                throws java.lang.Exception

  Throws:
    `java.lang.Exception`

### getMethodInfo

    javax.el.MethodInfo getMethodInfo(EvaluationContext ctx,
                                      java.lang.Class[] paramTypes)
                                      throws javax.el.ELException

  Throws:
    `javax.el.ELException`

### invoke

    java.lang.Object invoke(EvaluationContext ctx,
                            java.lang.Class[] paramTypes,
                            java.lang.Object[] paramValues)
                            throws javax.el.ELException
