java.lang.Object

com.oracle.js.parser.ir.Node

com.oracle.js.parser.ir.CaseNode

All Implemented Interfaces:

Terminal, Cloneable

public final class CaseNode
extends Node
implements Terminal

IR representation of case clause. Case nodes are not BreakableNodes, but the SwitchNode is.

Method Summary

Modifier and Type	Method	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.
List<Statement>	getStatements()	Get the body for this case node
Expression	getTest()	Get the test expression for this case node
boolean	isTerminal()	Returns true if this AST node is (or contains) a statement that terminates function control flow.
CaseNode	setStatements(List<Statement> statements)
CaseNode	setTest(Expression test)	Reset the test expression for this case node
void	toString(StringBuilder sb, boolean printTypes)	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 Details

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 printTypes)

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

printTypes - print type?

isTerminal

public boolean isTerminal()

Description copied from interface: Terminal

Returns true if this AST node is (or contains) a statement that terminates function control flow.

Specified by:

isTerminal in interface Terminal

getStatements

public List<Statement> getStatements()

Get the body for this case node

Returns:

the body

getTest

public Expression getTest()

Get the test expression for this case node

Returns:

the test

setTest

public CaseNode setTest(Expression test)

Reset the test expression for this case node

Parameters:

test - new test expression
