All Implemented Interfaces:

NodeMetaDataHandler, LoopingStatement

public class WhileStatement
extends Statement
implements LoopingStatement

Represents a while (condition) { ... } loop in Groovy. The while loop repeatedly evaluates a BooleanExpression at the start of each iteration and executes the loop body only if the condition is true. If the condition is false on the first evaluation, the loop body never executes.

Constructor Details

WhileStatement

public WhileStatement(BooleanExpression booleanExpression,
 Statement loopBlock)

Constructs a WhileStatement with a condition and loop body.

Parameters:

booleanExpression - the BooleanExpression evaluated at the start of each iteration

loopBlock - the Statement to execute while the condition is true

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

getBooleanExpression

public BooleanExpression getBooleanExpression()

Returns the BooleanExpression that is evaluated at the start of each iteration.

Returns:

the loop condition BooleanExpression}

getLoopBlock

public Statement getLoopBlock()

Returns the loop body Statement}.

Specified by:

getLoopBlock in interface LoopingStatement

Returns:

the loop block Statement}

setBooleanExpression

public void setBooleanExpression(BooleanExpression booleanExpression)

Sets the BooleanExpression} to evaluate at the start of each iteration.

Parameters:

booleanExpression - the loop condition BooleanExpression}

setLoopBlock

public void setLoopBlock(Statement loopBlock)

Sets the loop body Statement}.

Specified by:

setLoopBlock in interface LoopingStatement

Parameters:

loopBlock - the loop block Statement}
