Constructor Detail

JavaNodeFactory

public JavaNodeFactory()

Creates a new JavaNodeFactory object.

Method Detail

addASTChild

public void addASTChild(ASTPair currentAST,
                        AST child)

Add the given node as a child to the given root.

Overrides:

addASTChild in class ASTFactory

Parameters:

currentAST - root pair.

child - new child to add.

create

public AST create()

Creates a new empty JavaNode node.

Overrides:

create in class ASTFactory

Returns:

newly created Node.

create

public AST create(int type)

Creates a new JavaNode node.

Overrides:

create in class ASTFactory

Parameters:

type - information to setup the node with.

Returns:

newly created Node.

create

public AST create(AST node)

Creates a new JavaNode node.

Overrides:

create in class ASTFactory

Parameters:

node - node to setup the new node with.

Returns:

newly created Node.

create

public AST create(Token token)

Creates a new JavaNode node.

Overrides:

create in class ASTFactory

Parameters:

token - token to setup the new node with.

Returns:

newly created Node.

create

public AST create(int type,
                  String text)

Creates a new JavaNode node.

Overrides:

create in class ASTFactory

Parameters:

type - type information to setup the node with.

text - text to setup the node with.

Returns:

newly created Node.

dupList

public AST dupList(AST t)

Duplicate the given tree (including all siblings of root).

Overrides:

dupList in class ASTFactory

Parameters:

t - the root node of the tree (or tree portion)

Returns:

the copy of the tree.

dupTree

public AST dupTree(AST t)

Duplicate a tree, assuming this is a root node of a tree -- duplicates that node and what's below; ignore siblings of root node.

Overrides:

dupTree in class ASTFactory

Parameters:

t - the root node of the tree (or tree portion)

Returns:

the copy of the tree.

error

public void error(String message)

Logs the given error message.

Overrides:

error in class ASTFactory

Parameters:

message - an error message.

make

public AST make(AST[] nodes)

Makes a tree from a list of nodes. The first element in the array is the root. If the root is null, then the tree is actually a simple list not a tree. Handles null children nodes correctly. For example, build(a, b, null, c) yields tree (a b c). build(null,a,b) yields tree (nil a b).

Sets also the line/column info of the root node.

Overrides:

make in class ASTFactory

Parameters:

nodes - the nodes to create the tree with.

Returns:

the generated tree.

makeASTRoot

public void makeASTRoot(ASTPair currentAST,
                        AST root)

DOCUMENT ME!

Overrides:

makeASTRoot in class ASTFactory

Parameters:

currentAST - DOCUMENT ME!

root - DOCUMENT ME!
