Method Summary

Modifier and Type	Method and Description
Node	accept(NodeVisitor<? extends LexicalContext> visitor) Assist in IR navigation.
<R> R	accept(TranslatorNodeVisitor<? extends LexicalContext,R> visitor) Provides a means to navigate the IR.
Expression	getAssignmentDest() Get assignment destination.
Expression	getAssignmentSource() Get the assignment source.
Expression	getExpression() Get the right hand side of this if it is inherited by a binary expression, or just the expression itself if still Unary
boolean	isAssignment() Is this an assignment - i.e.
boolean	isSelfModifying() Is this a self modifying assignment?
UnaryNode	setExpression(Expression expression) Reset the right hand side of this if it is inherited by a binary expression, or just the expression itself if still Unary
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

public UnaryNode(long token,
                 Expression rhs)

Constructor

Parameters:

token - token

rhs - expression

UnaryNode

public UnaryNode(long token,
                 int start,
                 int finish,
                 Expression expression)

Method Detail

isAssignment

public boolean isAssignment()

Is this an assignment - i.e. that mutates something such as a++

Overrides:

isAssignment in class Node

Returns:

true if assignment

isSelfModifying

public boolean isSelfModifying()

Description copied from class: Expression

Is this a self modifying assignment?

Overrides:

isSelfModifying in class Expression

Returns:

true if self modifying, e.g. a++, or a*= 17

getAssignmentDest

public Expression getAssignmentDest()

Description copied from interface: Assignment

Get assignment destination.

Specified by:

getAssignmentDest in interface Assignment<Expression>

Returns:

the assignment destination node

getAssignmentSource

public Expression getAssignmentSource()

Description copied from interface: Assignment

Get the assignment source.

Specified by:

getAssignmentSource in interface Assignment<Expression>

Returns:

the assignment source node

accept

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

Assist in IR navigation.

Specified by:

accept in class Node

Parameters:

visitor - IR navigating 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?

getExpression

public Expression getExpression()

Get the right hand side of this if it is inherited by a binary expression, or just the expression itself if still Unary

Returns:

right hand side or expression node

See Also:

BinaryNode

setExpression

public UnaryNode setExpression(Expression expression)

Reset the right hand side of this if it is inherited by a binary expression, or just the expression itself if still Unary

Parameters:

expression - right hand side or expression node

Returns:

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