All Implemented Interfaces:

public class ExpressionStatement
extends Statement

Represents an expression statement that executes an expression where the return value is ignored. An expression statement wraps an Expression for use as a statement in contexts where an expression must be treated as a statement (e.g., method calls, assignments, or other side-effect-producing expressions). The expression is evaluated and its result is discarded.

Constructor Details

ExpressionStatement

public ExpressionStatement(Expression expression)

Constructs an expression statement with the given expression.

Parameters:

expression - the Expression to execute; must not be null

Throws:

IllegalArgumentException - if the expression is null

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

getExpression

public Expression getExpression()

Returns the expression executed by this statement.

Returns:

the Expression

setExpression

public void setExpression(Expression expression)

Sets the expression executed by this statement.

Parameters:

expression - the Expression

getText

public String getText()

Description copied from class: ASTNode

Returns a human-readable text representation of this AST node. Used for debugging and error messages. Default implementation returns a message indicating the representation is not yet implemented for this node type.

Overrides:

getText in class ASTNode

Returns:

text representation of this node, or placeholder for unimplemented types

toString

public String toString()

Overrides:

toString in class Object
