Fields in org.apache.commons.jexl.parser declared as Node

protected Node	SimpleNode.parent parent node.
protected Node[]	SimpleNode.children children of this node.

Methods in org.apache.commons.jexl.parser that return Node

Node	Node.jjtGetParent() Gets the parent node.
Node	Node.jjtGetChild(int i) This method returns a child node.
Node	SimpleNode.jjtGetParent() Gets the parent node.
Node	SimpleNode.jjtGetChild(int i) This method returns a child node. The children are numbered from zero, left to right.

Methods in org.apache.commons.jexl.parser with parameters of type Node

void	Node.jjtSetParent(Node n) This pair of methods are used to inform the node of its parent.
void	Node.jjtAddChild(Node n, int i) This method tells the node to add its argument to the node's list of children.
void	SimpleNode.jjtSetParent(Node n) This pair of methods are used to inform the node of its parent.
void	SimpleNode.jjtAddChild(Node n, int i) This method tells the node to add its argument to the node's list of children.
