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 ClosureExpression

Parameters:

visitor - the GroovyCodeVisitor to process this node

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 ClosureExpression

Returns:

text representation of this node, or placeholder for unimplemented types

isSerializable

public boolean isSerializable()

setSerializable

public void setSerializable(boolean serializable)
