Constructor Detail

NodeFactory

public NodeFactory(CompositeFactory compositeFactory)

Creates a new NodeFactory object.

Method Detail

create

public antlr.collections.AST create()

Creates a new empty JavaNode node.

Overrides:

create in class antlr.ASTFactory

Returns:

newly created Node.

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

create

public antlr.collections.AST create(int type)

Creates a new empty Node 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(int type,
                                    java.lang.String text)

Creates a new empty Node 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.

create

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

Creates a new empty Node 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 tok)

Creates a new empty Node node.

Overrides:

create in class antlr.ASTFactory

Parameters:

tok - token to setup the new node with.

Returns:

newly created Node.
