Method Summary

Modifier and Type	Method and Description
Node	accept(NodeVisitor<? extends LexicalContext> visitor) Provides a means to navigate the IR.
<R> R	accept(TranslatorNodeVisitor<? extends LexicalContext,R> visitor) Provides a means to navigate the IR.
Expression	getIndex() Get the index expression for this IndexNode
IndexNode	setIndex(Expression index) Set the index expression for this node
IndexNode	setIsSuper() Mark this node as being a SuperProperty access.
void	toString(StringBuilder sb, boolean printType) Print logic that decides whether to show the optimistic type or not - for example it should not be printed after just parse, when it hasn't been computed, or has been set to a trivially provable value

Method Detail

accept

public Node accept(NodeVisitor<? extends LexicalContext> visitor)

Description copied from class: Node

Provides a means to navigate the IR.

Specified by:

accept in class Node

Parameters:

visitor - Node visitor.

Returns:

node the node or its replacement after visitation, null if no further visitations are required

accept

public <R> R accept(TranslatorNodeVisitor<? extends LexicalContext,R> visitor)

Description copied from class: Node

Provides a means to navigate the IR.

Specified by:

accept in class Node

Parameters:

visitor - Node visitor.

Returns:

node the node or its replacement after visitation, null if no further visitations are required

toString

public void toString(StringBuilder sb,
                     boolean printType)

Description copied from class: Node

Print logic that decides whether to show the optimistic type or not - for example it should not be printed after just parse, when it hasn't been computed, or has been set to a trivially provable value

Specified by:

toString in class Node

Parameters:

sb - string builder

printType - print type?

getIndex

public Expression getIndex()

Get the index expression for this IndexNode

Returns:

the index

setIndex

public IndexNode setIndex(Expression index)

Set the index expression for this node

Parameters:

index - new index expression

Returns:

a node equivalent to this one except for the requested change.

setIsSuper

public IndexNode setIsSuper()

Description copied from class: BaseNode

Mark this node as being a SuperProperty access.

Specified by:

setIsSuper in class BaseNode
