Method Summary

Modifier and Type	Method	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 Details

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
