All Implemented Interfaces:

NodeMetaDataHandler

public class CaseStatement
extends Statement

Represents a case arm of a SwitchStatement or a SwitchExpression. A case consists of a pattern (expression) to match against the switch selector and the statement to execute if the pattern matches.

Constructor Summary

Constructors

Constructor	Description
CaseStatement(Expression expression, Statement code)	Constructs a case statement with the given expression pattern and code block.

Method Summary

Modifier and Type	Method	Description
Statement	getCode()	Returns the statement executed if this case pattern matches.
Expression	getExpression()	Returns the pattern expression matched against the switch control expression.
boolean	isArrow()	Indicates whether this case uses an arrow label (case L ->) rather than a colon label (case L:).
void	setArrow(boolean arrow)	Marks this case as an arrow label (case L ->) or a colon label.
void	setCode(Statement code)	Sets the statement executed if this case pattern matches.
void	setExpression(Expression e)	Sets the pattern expression matched against the switch control expression.
String	toString()
void	visit(GroovyCodeVisitor visitor)	Accepts a code visitor for AST traversal and transformation.

Constructor Details

CaseStatement

public CaseStatement(Expression expression,
 Statement code)

Constructs a case statement with the given expression pattern and code block.

Parameters:

expression - the Expression pattern to match against the switch control expression

code - the Statement to execute if the pattern matches

Method Details

getCode

public Statement getCode()

Returns the statement executed if this case pattern matches.

Returns:

the Statement associated with this case

setCode

public void setCode(Statement code)

Sets the statement executed if this case pattern matches.

Parameters:

code - the Statement to execute

getExpression

public Expression getExpression()

Returns the pattern expression matched against the switch control expression.

Returns:

the pattern Expression

setExpression

public void setExpression(Expression e)

Sets the pattern expression matched against the switch control expression.

Parameters:

e - the pattern Expression

isArrow

public boolean isArrow()

Indicates whether this case uses an arrow label (case L ->) rather than a colon label (case L:). Arrow labels do not fall through (JEP 361).

Returns:

true if this case was written with ->

Since:

6.0.0

setArrow

public void setArrow(boolean arrow)

Marks this case as an arrow label (case L ->) or a colon label.

Parameters:

arrow - true if this case was written with ->

Since:

6.0.0

visit

public void visit(GroovyCodeVisitor visitor)

Description copied from class: ASTNode

Accepts a code visitor for AST traversal and transformation. Subclasses must implement this method to support visitor pattern-based processing. The visitor pattern enables decoupling of AST structure from processing logic.

Overrides:

visit in class ASTNode

Parameters:

visitor - the GroovyCodeVisitor to process this node

toString

public String toString()

Overrides:

toString in class Object
