Class SynchronizedStatement

org.codehaus.groovy.ast.ASTNode

org.codehaus.groovy.ast.stmt.Statement

org.codehaus.groovy.ast.stmt.SynchronizedStatement

All Implemented Interfaces:

NodeMetaDataHandler

public class SynchronizedStatement
extends Statement

Represents a synchronized statement that provides mutual exclusion for a code block. A synchronized statement acquires a lock on the monitor associated with the control expression before executing the code block, ensuring that only one thread can execute the synchronized block at a time for the given monitor object.

Constructor Summary

Constructors

Constructor	Description
SynchronizedStatement(Expression expression, Statement code)	Constructs a synchronized statement with the given monitor expression and code block.

Method Summary

Modifier and Type	Method	Description
Statement	getCode()	Returns the statement executed within the synchronized block.
Expression	getExpression()	Returns the monitor expression whose lock is acquired for synchronization.
void	setCode(Statement statement)	Sets the statement executed within the synchronized block.
void	setExpression(Expression expression)	Sets the monitor expression whose lock is acquired for synchronization.
void	visit(GroovyCodeVisitor visitor)	Accepts a code visitor for AST traversal and transformation.

Constructor Details

SynchronizedStatement

public SynchronizedStatement(Expression expression,
 Statement code)

Constructs a synchronized statement with the given monitor expression and code block.

Parameters:

expression - the Expression that evaluates to the monitor object to synchronize on

code - the Statement to execute under mutual exclusion

Method Details

getCode

public Statement getCode()

Returns the statement executed within the synchronized block.

Returns:

the Statement executed under mutual exclusion

setCode

public void setCode(Statement statement)

Sets the statement executed within the synchronized block.

Parameters:

statement - the Statement to execute under mutual exclusion

getExpression

public Expression getExpression()

Returns the monitor expression whose lock is acquired for synchronization.

Returns:

the monitor Expression

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

setExpression

public void setExpression(Expression expression)

Sets the monitor expression whose lock is acquired for synchronization.

Parameters:

expression - the monitor Expression
