public class SimpleNode
extends YamNode
implements Node

Node implementation class mostly generated by JJTree. Altered to

• inherit from YamNode (for additional state and behaviour related to translation)
• print / dump differently
• add getId method
• add addChildren method

Method Detail

getId

public int getId()

Get the id of this node.

hasChildren

public boolean hasChildren()

Does this node have children?

jjtOpen

public void jjtOpen()

Description copied from interface: Node

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

Specified by:

jjtOpen in interface Node

jjtClose

public void jjtClose()

Description copied from interface: Node

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

Specified by:

jjtClose in interface Node

jjtSetParent

public void jjtSetParent(Node n)

Description copied from interface: Node

This pair of methods are used to inform the node of its parent.

Specified by:

jjtSetParent in interface Node

jjtGetParent

public Node jjtGetParent()

Specified by:

jjtGetParent in interface Node

jjtAddChild

public void jjtAddChild(Node n,
                        int i)

Description copied from interface: Node

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

Specified by:

jjtAddChild in interface Node

jjtGetChild

public Node jjtGetChild(int i)

Description copied from interface: Node

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

Specified by:

jjtGetChild in interface Node

jjtGetNumChildren

public int jjtGetNumChildren()

Description copied from interface: Node

Return the number of children the node has.

toString in class Object

toString

public String toString(String prefix)

dump

public void dump(String prefix)

Print the node.

getImage

public String getImage()

Return the image of the node, based on the concatenation of its tokens.

addChildren

public void addChildren(Node other)
