All known Subclasses: ognl.SimpleNode,
| Node | | public interface Node (Code) | | JJTree interface for AST nodes, as modified to handle the OGNL operations getValue and
setValue. JJTree's original comment:
All AST nodes must implement this interface. It provides basic
machinery for constructing the parent and child relationships
between nodes.

| Method Summary | |
| public Object | getValue(OgnlContext context, Object source)
Extracts the value from the given source object that is appropriate for this node
within the given context. | | public void | jjtAddChild(Node n, int i)
This method tells the node to add its argument to the node's
list of children. | | public void | jjtClose()
This method is called after all the child nodes have been
added. | | public Node | jjtGetChild(int i)
This method returns a child node. | | public int | jjtGetNumChildren()
Return the number of children the node has. | | public Node | jjtGetParent()
| | public void | jjtOpen()
This method is called after the node has been made the current
node. | | public void | jjtSetParent(Node n)
This pair of methods are used to inform the node of its
parent. | | public void | setValue(OgnlContext context, Object target, Object value)
Sets the given value in the given target as appropriate for this node within the
given context. |
| jjtAddChild | | public void jjtAddChild(Node n, int i)(Code) | | This method tells the node to add its argument to the node's
list of children.
|
| jjtClose | | public void jjtClose()(Code) | | This method is called after all the child nodes have been
added.
|
| jjtGetChild | | public Node jjtGetChild(int i)(Code) | | This method returns a child node. The children are numbered
from zero, left to right.
|
| jjtGetNumChildren | | public int jjtGetNumChildren()(Code) | | Return the number of children the node has.
|
| jjtOpen | | public void jjtOpen()(Code) | | This method is called after the node has been made the current
node. It indicates that child nodes can now be added to it.
|
| jjtSetParent | | public void jjtSetParent(Node n)(Code) | | This pair of methods are used to inform the node of its
parent.
