public interface IJevaNode

extends Node

IJevaNode: extends Node with methods for accessing the tokens and for printing out the token stream for this node.

Method Summary

Token	getBeginToken()
Token	getEndToken()
void	insertNewChildAfter(IJevaNode newChild, IJevaNode oldChild) Insert new child, linking in token stream just after old child.
void	insertNewChildAt(IJevaNode newChild, int position, Token beginHole) insert new child, linking in token stream just after beginHole.
void	insertNewChildBefore(IJevaNode newChild, IJevaNode oldChild) Insert new child, linking in token stream just before old child.
Object	jjtAccept(IJevaVisitor visitor, Object data) Accept a visitor.
IJevaNode	jnGetChild(int i) jnGetChild is like Node.jjtGetChild except it returns an IJevaNode
IJevaNode	jnGetParent() jnGetParent is like Node.jjtGetParent except it returns an IJevaNode
void	print(PrintWriter stream) Print tokens of parsed node's syntax, including children, to stream.
void	print(PrintWriter stream, boolean includeSpecialTokens)
String	printToString() Print tokens of parsed node's syntax, including children, to string.
String	printToString(boolean includeSpecialTokens)
void	removeChild(IJevaNode child) remove a child node and remove its tokens from token chain.
void	replaceChild(IJevaNode oldChild, IJevaNode newChild) remove a child node and replace it with new child; also in token chain
void	replaceChild(int index, IJevaNode oldChild, IJevaNode newChild)
void	setBeginToken(Token t) Called by the parser to set the first token of the parsed syntax
void	setEndToken(Token t) Called by the parser to set the last+1 token of the parsed syntax

Method Detail

getBeginToken

public Token getBeginToken()

Returns:

the first token (in token chain) of the parsed syntax

getEndToken

public Token getEndToken()

Returns:

the token after the last token of the parsed syntax

setBeginToken

public void setBeginToken(Token t)

Called by the parser to set the first token of the parsed syntax

setEndToken

public void setEndToken(Token t)

Called by the parser to set the last+1 token of the parsed syntax

print

public void print(PrintWriter stream)

Print tokens of parsed node's syntax, including children, to stream. also prints special tokens (whitespace and comments)

print

public void print(PrintWriter stream,
                  boolean includeSpecialTokens)

printToString

public String printToString()

Print tokens of parsed node's syntax, including children, to string. Includes special tokens (whitespace and comments).

Returns:

a string recreating node's syntax

printToString

public String printToString(boolean includeSpecialTokens)

jjtAccept

public Object jjtAccept(IJevaVisitor visitor,
                        Object data)

Accept a visitor. For visitor design pattern: jjtAccept must simply

  return visitor.visit(this, data);  

which dispatches on the type of this to appropriate method of visitor

jnGetChild

public IJevaNode jnGetChild(int i)

jnGetChild is like Node.jjtGetChild except it returns an IJevaNode

jnGetParent

public IJevaNode jnGetParent()

jnGetParent is like Node.jjtGetParent except it returns an IJevaNode

removeChild

public void removeChild(IJevaNode child)

remove a child node and remove its tokens from token chain.

replaceChild

public void replaceChild(IJevaNode oldChild,
                         IJevaNode newChild)

remove a child node and replace it with new child; also in token chain

replaceChild

public void replaceChild(int index,
                         IJevaNode oldChild,
                         IJevaNode newChild)

insertNewChildAfter

public void insertNewChildAfter(IJevaNode newChild,
                                IJevaNode oldChild)

Insert new child, linking in token stream just after old child.

insertNewChildBefore

public void insertNewChildBefore(IJevaNode newChild,
                                 IJevaNode oldChild)

Insert new child, linking in token stream just before old child.

insertNewChildAt

public void insertNewChildAt(IJevaNode newChild,
                             int position,
                             Token beginHole)

insert new child, linking in token stream just after beginHole.
