public class CatchStatement
extends Statement

Represents a catch (Exception var) { } statement that handles exceptions in a try-catch block. Each catch statement specifies an exception type to handle and a code block to execute when an exception of that type is caught. The exception is bound to a variable that can be referenced within the catch block.

Constructor Details

CatchStatement

public CatchStatement(Parameter variable,
 Statement code)

Constructs a catch statement with the given exception parameter and code block.

Parameters:

variable - the Parameter that declares the caught exception and binds it to a variable name

code - the Statement to execute when the exception is caught

Method Details

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

getCode

public Statement getCode()

Returns the statement executed when the exception is caught.

Returns:

the catch block Statement

getExceptionType

public ClassNode getExceptionType()

Returns the exception type of this catch statement.

Returns:

the ClassNode representing the exception type

getVariable

public Parameter getVariable()

Returns the parameter that declares the caught exception variable.

Returns:

the exception Parameter

setCode

public void setCode(Statement code)

Sets the statement executed when the exception is caught.

Parameters:

code - the catch block Statement
