public interface ParseTree

The ParseTree class presents for the node of parse tree. This may be a token node, Leaf, or may be a nonterminal node, NonLeaf.

Leaf, NonLeaf

Method Summary

void	accept(ParseTreeVisitor visitor) Accepts a ParseTreeVisitor object as the role of a Visitor in the Visitor pattern, as the role of an Element in the Visitor pattern.
void	childrenAccept(ParseTreeVisitor visitor) Accepts a ParseTreeVisitor object as the role of a Visitor in the Visitor pattern, as the role of an Element in the Visitor pattern.
boolean	eq(ParseTree p) Tests if this parse-tree-node's value equals to the specified ptree-node's.
boolean	equals(ParseTree p) Tests if this parse-tree-node's value equals to the specified ptree-node's.
int	getObjectID() Returns the Identifier Number of this object
ParseTree	makeCopy() Makes a new copy of this nonleaf-node as a ptree-node.
ParseTree	makeRecursiveCopy() Makes a new copy (another object) of this nonleaf-node recursively.
void	replace(ParseTree replacement)
String	toFlattenString() Generates the string expression from this node.
String	toString() Generates string which presents for this parse-tree
void	writeCode() Deprecated.

Method Detail

replace

public void replace(ParseTree replacement)
             throws ParseTreeException

ParseTreeException

makeRecursiveCopy

public ParseTree makeRecursiveCopy()

Makes a new copy (another object) of this nonleaf-node recursively. The objects contained by this object will also be copied.

Returns:

the copy of this nonleaf-node as a ptree-node.

makeCopy

public ParseTree makeCopy()

Makes a new copy of this nonleaf-node as a ptree-node. The objects contained by the new object are same as these contained by the original object.

Returns:

the copy of this nonleaf-node as a ptree-node.

equals

public boolean equals(ParseTree p)

Tests if this parse-tree-node's value equals to the specified ptree-node's.

Returns:

true if two values are same.

eq

public boolean eq(ParseTree p)

Tests if this parse-tree-node's value equals to the specified ptree-node's.

Returns:

true if two this and p refer to the same ptree object.

toString

public String toString()

Generates string which presents for this parse-tree

Overrides:

toString in class Object

Returns:

string which presents for this parse-tree

writeCode

public void writeCode()

Deprecated.

toFlattenString

public String toFlattenString()

Generates the string expression from this node. Returned string doesn't have '"' without cancel ( \" ) and doesn't have newline.

This method is useful to embed ptree objects as a string literal in source code.

Returns:

the flatten string which this node represents

getObjectID

public int getObjectID()

Returns the Identifier Number of this object

Returns:

the ID number of this object

accept

public void accept(ParseTreeVisitor visitor)
            throws ParseTreeException

Accepts a ParseTreeVisitor object as the role of a Visitor in the Visitor pattern, as the role of an Element in the Visitor pattern.

This invoke an appropriate visit() method on the accepted visitor.

Parameters:

visitor - a visitor

ParseTreeException

childrenAccept

public void childrenAccept(ParseTreeVisitor visitor)
                    throws ParseTreeException

Accepts a ParseTreeVisitor object as the role of a Visitor in the Visitor pattern, as the role of an Element in the Visitor pattern.

This invoke an appropriate visit() method on each child ParseTree object with this visitor.

Parameters:

visitor - a visitor
