Constructor Detail

JavaNodeFactory

public JavaNodeFactory(CompositeFactory compositeFactory)

Creates a new JavaNodeFactory object.

Method Detail

addASTChild

public void addASTChild(antlr.ASTPair currentAST,
                        antlr.collections.AST child)

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

Overrides:

addASTChild in class antlr.ASTFactory

Parameters:

currentAST - root pair.

child - new child to add. TODO Examine what this does ?

create

public antlr.collections.AST create(int type)

Creates a new JavaNode node.

Overrides:

create in class antlr.ASTFactory

Parameters:

type - information to setup the node with.

Returns:

newly created Node.

create

public antlr.collections.AST create(antlr.collections.AST node)

Creates a new JavaNode node.

Overrides:

create in class antlr.ASTFactory

Parameters:

node - node to setup the new node with.

Returns:

newly created Node.

create

public antlr.collections.AST create(antlr.Token token)

Creates a new JavaNode node.

Overrides:

create in class antlr.ASTFactory

Parameters:

token - token to setup the new node with.

Returns:

newly created Node.

create

public antlr.collections.AST create(int type,
                                    java.lang.String text)

Creates a new JavaNode node.

Overrides:

create in class antlr.ASTFactory

Parameters:

type - type information to setup the node with.

text - text to setup the node with.

Returns:

newly created Node.

dupList

public antlr.collections.AST dupList(antlr.collections.AST t)

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

Overrides:

dupList in class antlr.ASTFactory

Parameters:

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

Returns:

the copy of the tree.

dup

public antlr.collections.AST dup(antlr.collections.AST t)

Copy a single node with same Java AST objec type. Ignore the tokenType->Class mapping since you know the type of the node, t.getClass(), and doing a dup. clone() is not used because we want all AST creation to go thru the factory so creation can be tracked. Returns null if t is null.

Overrides:

dup in class antlr.ASTFactory

dupTree

public antlr.collections.AST dupTree(antlr.collections.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 antlr.ASTFactory

Parameters:

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

Returns:

the copy of the tree.

error

public void error(java.lang.String message)

Logs the given error message.

Overrides:

error in class antlr.ASTFactory

Parameters:

message - an error message.

make

public antlr.collections.AST make(antlr.collections.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 antlr.ASTFactory

Parameters:

nodes - the nodes to create the tree with. TODO Examine what this does

Returns:

the generated tree.

makeASTRoot

public void makeASTRoot(antlr.ASTPair currentAST,
                        antlr.collections.AST root)

DOCUMENT ME!

Overrides:

makeASTRoot in class antlr.ASTFactory

Parameters:

currentAST - DOCUMENT ME!

root - DOCUMENT ME!

create

public JavaNode create(int startLine,
                       int startColumn,
                       int endLine,
                       int endColumn)
