Interface Node

All Known Implementing Classes:

NodeCondition, NodeLogical, NodeQuery, NodeSimpleQuery, SimpleNode

public interface Node

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

Method Summary

void	jjtAddChild(Node n, int i) This method tells the node to add its argument to the node's list of children.
void	jjtClose() This method is called after all the child nodes have been added.
Node	jjtGetChild(int i) This method returns a child node.
int	jjtGetNumChildren() Return the number of children the node has.
Node	jjtGetParent() This method and jjtSetParent(net.sourceforge.nite.search.Node) are used to inform the node of its parent.
void	jjtOpen() This method is called after the node has been made the current node.
void	jjtSetParent(Node n) This method and jjtGetParent() are used to inform the node of its parent.

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 method and jjtGetParent() are used to inform the node of its parent.

Parameters:

n - parent

jjtGetParent

Node jjtGetParent()

This method and jjtSetParent(net.sourceforge.nite.search.Node) are used to inform the node of its parent.

Returns:

parent

jjtAddChild

void jjtAddChild(Node n,
                 int i)

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

Parameters:

n - the child node to be add

i - position to insert

jjtGetChild

Node jjtGetChild(int i)

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

Parameters:

i - number of the child

Returns:

the requested child

jjtGetNumChildren

int jjtGetNumChildren()

Return the number of children the node has.

Returns:

the number of children the node has
