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.
int	getIndex() Formal parameter index.
boolean	isRestParameter() If true, this is a rest parameter.
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 int getIndex()

Formal parameter index.

isRestParameter

public boolean isRestParameter()

If true, this is a rest parameter.
